FREQUENTLY ASKED QUESTIONS ABOUT TEETH WHITENING

1. What are the most suitable methods for whitening my teeth?

For teeth whitening, there are types of teeth whitening methods that you can apply at home, called home type, which are applied in the clinic, which is basically called office type.

“Office type teeth whitening” can be done in two ways. The dentist uses a strong whitening gel alone or in combination with a laser. Together with the two, the dentist first cleans the surface of your teeth to remove plaque from your teeth. A peroxide-based teeth whitening gel is then applied, usually with the help of light to aid the whitening process. Although most gels are used alone, some need an additional light source. Laser does not whiten the tooth alone. It only activates the whitening gel and initiates the necessary chemical reaction (it does not penetrate into the tooth). This process takes around 30-45 minutes and although it gives immediate results, more than one session may be required to achieve the desired whiteness level.

At-home teeth whitening requires a mold that allows the tooth whitening gel to stay in contact with the tooth overnight or for several hours, depending on the strength of the tooth whitening gel. There are ready-made molds sold in places such as pharmacies, etc. Instead of these, it is much more accurate to apply a plate made according to your mouth, if possible. Before using them, your dentist should examine you before the whitening process for cavities or other things that will affect the teeth whitening results and perform your treatments if necessary.

Whichever method is used, how much your teeth will whiten depends on the initial color and the source of the discoloration. Brown and yellow teeth (caused by coffee, cigarettes and tea.) generally give better results. Teeth with gray tones (which are caused by pigments in the tooth, not stains) turn less white. Results cannot be guaranteed. To understand the initial color of your teeth, your dentist can take the color of your tooth and measure it using a color scale or take a photograph.

Home-use teeth whitening kits can be purchased from dentists and you can use them whenever you want. The sets that can be bought from pharmacies are less expensive, but they are not very effective by dentists and the product your dentist recommends will be more effective in terms of content. The most known side effect is hot-cold sensitivity during and 1-2 days after teeth whitening. If you think you’ll forget to put the mold on your teeth every evening or don’t want to wait too long to wait for the results, in-office teeth whitening may be a better solution for you. This solution also allows the dentist to take care of your teeth individually if your teeth are different from each other in color. The most effective method known is to use office type teeth whitening and home type together. With proper care, whitened teeth stay bright for several years. To keep your teeth as white as possible, you can try these methods:

Follow the white tooth diet: Choose white instead of red wine, cappuccino instead of espresso, light-colored instead of dark juice.

Use toothpaste that contains peroxide or has whitening properties.

2. I have very sensitive teeth, does whitening cause tooth sensitivity and if so, how can it be treated?

Are your teeth sensitive from using whitening gel? Or is there normal hypersensitivity? If there is tooth sensitivity before the teeth whitening process, then your dentist should start teeth whitening after the results of the desensitizing treatment are obtained. Otherwise, the teeth whitening process may not be suitable for you. One of the most confusing situations is the sensitivity of a tooth decay that is present in the mouth but not noticed, your dentist will determine this.

3. Does Teeth Whitening harm the teeth, is it safe?

Studies and microscopic studies have shown that there is no harm in the long-term use of 10% home bleaching solution. Some risks arise with methods that are very new and whose safety has not yet been tested, or by applying this process too often or too heavily. I suggest you act according to your doctor’s advice on this matter. Controlled application and timely removal of the gel applied inside the tooth is very important in single tooth discoloration, otherwise there is a risk of root resorption. In addition, it is not recommended to keep the gel in the mouth all night in home teeth whitening. The gel is not good to swallow and is safer to apply for a few hours while awake instead.

4. Are there any side effects of teeth whitening?

Teeth whitening gels can cause more or less temporary tooth sensitivity. Sensitivity to these cold hot drinks and even the air is uncomfortable. This is a normal and expected side effect. Some brands contain ingredients that are claimed to reduce post-whitening sensitivity. If tooth sensitivity does not go away within 24-48 hours, it is recommended to stop using whitener. In case of sensitivity, fluoride that your dentist will apply and toothpaste or creams that he will recommend to you will reduce this tooth sensitivity. Toothpastes containing potassium nitrate and arginine also work to reduce sensitivity.

5. Why is teeth whitening not recommended for pregnant women or those who have just given birth?

No research has been done on this subject, and manufacturers do not recommend this procedure to be done by pregnant and lactating mothers. The effects on the baby may cause problems in the future.

6. How long will it take for my teeth to whiten?

Results are different and vary from person to person. Some teeth whiten in a day or two, while others may take a month or two. Most people’s teeth whiten in 2-3 weeks. The more yellowing your teeth are without graying, the better the whitening will be. Graying caused by the use of antibiotics is more difficult to whiten and may require a longer process to achieve the result. If the result cannot be obtained, aesthetic porcelain application applied to the front surface of the teeth in the form of laminate veneers can be considered.

7. How long does teeth whitening last?

In general, after bleaching, the color first loses its brightness and fades slowly and remains stable between six months and two years. It is recommended to provide maintenance with 1-2 sessions every 4-6 months.

8. Will the whitening gel coating also whiten my porcelain crowns?

All whitening agents work on the natural tooth structure. This means that porcelain veneer crowns and bridges do not whiten. All this may need to change to match the color of your newly whitened tooth.

9. If I have a bridge or orthodontic wire in my tooth, is it okay to have teeth whitening?

Teeth whitening is more appropriate after your orthodontic (wire) treatment is finished. If you have a bridge prosthesis, it will not be a problem if it is in the posterior region, but if it is in the anterior region, this may cause a problem as your teeth will whiten and your porcelain will remain darker, in this case, it would be more appropriate to renew your bridge or crown if the time has come, and to do it according to the newly whitened color.

10. Which teeth whitening gel is better?

Currently, there is no research that impartially compares different teeth whitening systems. Although they all work, some gels can provide faster results. No matter what product is used, some teeth may whiten very well, although some teeth may whiten very little. My advice is to use the brand you used before or try a new brand if you are not satisfied. After all, the bleaching agent used is really a personal choice. In this choice, you can make the best decision together with your dentist, based on your previous experience.

11. What is the shelf life of Teeth Whitening gel?

The shelf life of the whitening gel is 2 years in the refrigerator and 1 year in the normal environment. The gel kept outside should be stored in a dry and cool environment. The amount used depends on the strength of the product. In addition, expiration dates are written on the products, the cold chain in office type teeth whitening gels should not be broken in general and the responsibility in this regard belongs to the medical companies and your dentist, it is reasonable to store home teeth whitening gels in the refrigerator outside the freezer.

12. Which teeth whitening gel is the most effective or fastest?

The active ingredient in most whitening products is the same or similar. Although some of them act a little faster, the working principles are the same. Some teeth can be cleaned more difficult than others, regardless of the product. As you get older and the gray tones on your teeth increase, the effect of the teeth whitening process will be harder and less results will be obtained. Teeth whitening may not give the desired result regardless of the product and brand used in some teeth. At this point, it would be more accurate to determine your expectations with your dentist.

13. How many whitening syringes do I need to buy to whiten my teeth at home?

Since the amount of substance in the syringe of each brand is different, ml instead of syringe. and cc. It will be easier to use. Generally 0.5 ml per session. whitening gel is sufficient. So the average person with yellow teeth will need 10-15 ml. Note that you need to have some available for maintenance later. Grayed teeth will be more difficult to clean, so more gel is required. Remember that a small drop is enough for the inner surface of the mold made where there are only 8 teeth. Since the teeth at the back of your mouth are not visible when smiling, it is not necessary to whiten them.

14. Do everyone’s teeth turn white at the same rate?

Everyone’s teeth whitening results are different. While whitening may be noticeable in some teeth in a few days, it may take weeks to be noticed in some teeth. The higher the amount of yellowing on the teeth before graying, the better results are obtained. Discoloration caused by the use of antibiotics is more difficult to remove. No matter what product you use on some teeth, whitening may not give a magnificent result. Results cannot be guaranteed. Your dentist will give you the right information about this.

15. Why are the parts close to the gums less white than the other parts of the tooth?

If you are using a home teeth whitening product; Make sure the whitener covers all parts of the tooth, not just the bottom. The average tooth goes from white to less white in areas close to the gums. This is a normal and predicted result. This is due to the thinner enamel in this area. In other words, there may be a darker dentin layer reflected from the inside at the bottom. This transition may be less noticeable in grayed teeth. Remember that this difference in color will get mixed in time.

16. Even though I’m new to whitening, it doesn’t hold up properly due to speckles and white spots. Should I continue whitening or stop?

It is normal for some areas of the tooth, such as decalcification areas, to react more quickly to the whitener and produce white spots. After the whitening is finished, these whitenesses disappear and give a more harmonious image.

17. I have molds for teeth whitening, can I use new whitening gels?

Old plaques can be technically used for the new teeth whitening process, but it is useful to confirm that your teeth are suitable by consulting your dentist again before the teeth whitening process.

18. What do the different percentages used mean?

The percentages(%’s) used mean the ratio of the bleaching agent. In general, the product with a higher percentage has more power and effect. However, there is no research to support this opinion. An advantage of high percentages is the use and duration of action. 10-16% can be used from a few hours to overnight, while 20-22% can be used for a few hours per session. Depending on the content and contents of teeth whitening systems, your dentist will guide you in the most accurate way about duration and application.

19. What is the difference between carbamide peroxide and hydrogen peroxide teeth whitening gels?

There are two main whitening ingredients. Carbamide peroxide (Opalescence, fgm etc) and hydrogen peroxide (Day White, Zoom etc). In comparison, 7.5% hydrogen peroxide corresponds to 16% carbamide peroxide, while 9.5% hydrogen peroxide corresponds to 26% carbamide peroxide. Carbamide peroxide decomposes into hydrogen peroxide. The only difference between them is the duration of use.

20. How long should I stay away from coffee and red wine after bleaching?

You should stay away from these and other coloring foods for about 2 weeks after teeth whitening. In general, we recommend that you do a white tooth diet for the first two weeks. If you see that your teeth turn yellow over time, maintenance can be done every 6 months on average.

21. How long should I use the whitening gel?

When to finish whitening is a personal choice and will be finalized by your dentist’s decision. You can quit when you are satisfied with the results. Teeth whiten in a few days or 2 weeks and eventually reach a point where they can no longer whiten. This is the last point you will reach and it will not whiten any longer from here. It is normal for them to fade a little and then stay in a stable color. Usually no more than 3-4 weeks of whitening is recommended. Most teeth whiten well in the first week of treatment.

22. I have gray stained teeth and I want to whiten my teeth.

It is difficult to whiten the discoloration of tetracycline-like drugs. Results vary and cannot be guaranteed. If you have used one brand of whitener, it will not make much difference if you use another brand. When whitening teeth with tetracycline, sometimes uneven whitening or vertical lines with tetracycline may appear. In some cases, the teeth whitened properly, satisfying the user. Accepting the use of whitening products means accepting all the risks that come with the use. For teeth stained with tetracycline, it is recommended to see a dentist before cleaning, and it may take several months to see results.

23. How long can I whiten my tetracycline-stained teeth?

Up to 6 months of whitening is acceptable for normal teeth. Although some studies say that it can take up to 6 months to whiten teeth stained with tetracycline, we believe that 8 weeks will suffice. If your teeth are not whitening anymore, this is a good time to stop.

24. I’ve been brushing my teeth with baking soda for a few months now and my teeth are very sensitive right now. At my annual checkup, my dentist said that my teeth did not have gum recession or gum disease. What would you recommend for teeth whitening?

Having sensitive teeth all the time is not normal and they can be diagnosed and corrected. In order not to be responsible for this, the best thing to do is to go to the dentist. For tooth sensitivity on your own, we can recommend using any toothpaste that contains potassium nitrate, arginine, these are usually “sensitive teeth” etc. in the markets. Sold under the titles. Note that the recommended expiry times of these toothpastes are a few weeks. Nowadays, there are remineralization toothpastes that not only treat tooth sensitivity but also minor cavities thanks to remineralization.

Whitening creates tooth sensitivity and increases the sensitivity. Therefore, it is recommended to use a desensitizing toothpaste a few weeks before teeth whitening.

25. What does Fluoride or Potassium Fluoride in Toothpaste mean?

F stands for fluoride and PF stands for fluoride and potassium nitrate. Both are included in the whitening gel against tooth sensitivity. PF is more effective as it contains both potassium nitrate and fluoride. Although both whiten the same amount, PF is known to cause less sensitivity.

26. My children have mottled teeth. Does whitening work?

Mottled teeth are caused by excess fluoride during tooth development. This condition is called fluorosis. Although they may not look perfect, these teeth are resistant to decay. Spots can also be seen after orthodontic treatment. In the case of this decalcification caused by inadequate hygiene, these areas are more susceptible to caries.

No research has been done on children and whitening, but whitening procedures have been performed with no side effects except for temporary tooth sensitivity. For whitening, we recommend waiting until the teeth are fully erupted, otherwise the areas that have not erupted will not be whitened. Although the white dots whiten faster, the difference disappears as the area around them becomes whiter. White dots are more difficult to discern as the surrounding areas will be whiter. Results vary and cannot be guaranteed.

In general, if the pulp chamber (the part where the dental nerves are located) is too wide in children, teeth whitening is not recommended.

27. Although I used the teeth whitening gels I use at home twice a day as recommended, not exceeding one hour each, I fell asleep a few times during use. Now I feel that some parts of my teeth are straight and some parts are rough. Have I damaged my tooth enamel and if so is there a way to fix it?

Most research on whitening has found it to be safe at recommended time intervals. There are toothpastes on the market that provide remineralization containing essential minerals believed to be absorbed by the tooth surface. At the same time, it is recommended to use this type of toothpaste, which is known to be good for sensitivity, during whitening. In addition, in such a case, fluoride and similar supplements that your dentist will apply will be beneficial.

28. During whitening, my gums started to burn and are white in some places. Could this be from using too much gel?

Plaques can be either on the gums or very full. All you have to do is put a small drop of gel into the plaque on each tooth or teeth whitening line. The gums return to normal in a few hours and the whiteness disappears. Avoid re-whitening or bitter and spicy foods until the gums have healed. Use less time next time and increase gradually.

29. Do ready-made teeth whitening tapes cause sensitivity in the teeth?

Yes, all whitening products can cause sensitivity, but the sensitivity disappears after a few days of use. If your teeth are sensitive, use the teeth whitening strips once and repeat when the sensitivity decreases. Remember that all whitening agents can cause sensitization.

30. It is very difficult to spread teeth whitener on the molds I have made. Do you have any advice for distributing the teeth whitening gel more evenly?

What needs to be done is to spread the whitener on the inner side of the outer surface of the plaque in a long thin line, and it is necessary to pay attention to coincide with the outer surfaces of the front teeth as much as possible. Thus, the gel, which takes the form of a rope, does not overflow. When you place the plaque on your teeth, it will spread the teeth whitener.

You can see the places where the whitener covers the teeth, and if it is less in some places, you can play with the plate a little so that the gel spreads evenly. The gel should always be dense and fluid. The whitening gel you will buy in your routine already has these features. If you use a product with problems in this regard, you should consult your dentist.

Since teeth whitening gels are not usually kept at room temperature, their consistency will be dense. It is recommended to keep them at room temperature for a few hours to become more fluid.

31. How do we prevent the teeth whitening gel from leaking from the cap?

You can reduce the pressure in the syringe by pulling the back of the syringe a little after use. This will prevent overflow.
