While teeth whitening offers numerous aesthetic benefits, some patients may experience tooth sensitivity during the treatment. It’s important to know that this occurs in less than 50% of cases and always ceases at the end of the treatment. This article aims to explore the causes of this sensitivity and how it can be managed or prevented.
What is Teeth Whitening?
Teeth whitening is a popular and completely harmless treatment for tooth enamel and gums when used under the supervision of an experienced dentist. It can improve the appearance of your smile by making your teeth whiter. Whitening agents, such as hydrogen peroxide or carbamide peroxide, are used, which act by transporting oxygen through the enamel to the inner layer, the dentin (the darker part of the tooth); once inside, the oxygen is released and removes the colored particles of the tooth.
Why Can Teeth Whitening Cause Sensitivity?
Tooth sensitivity after whitening occurs when the oxygen in the whitening agents reaches the dentin, the layer beneath the tooth enamel, and stimulates the micro extensions of the tooth nerve. This sensitivity can manifest as mild pain or discomfort (always temporary) in the teeth, usually when consuming hot or cold foods or drinks. It rarely occurs spontaneously.
How to Prevent Tooth Sensitivity During Teeth Whitening
There are several measures you can take to prevent or minimize tooth sensitivity during teeth whitening:
1. Consult Your Dentist: Before undertaking any whitening treatment, it’s important to consult your dentist so they can examine the health of your teeth and advise you on the best whitening procedure for you.
2.Use Toothpaste for Sensitive Teeth: Some toothpastes are formulated specifically to reduce tooth sensitivity. You might start using one of these products a couple of weeks before the treatment. Products containing Potassium Nitrate have been proven excellent in managing or resolving dental hypersensitivity.
3.Avoid Extremely Cold or Hot Foods and Drinks: If your teeth are sensitive, avoiding very cold or hot foods and drinks can help prevent discomfort. At least during the course of the treatment itself.
4.Use a Straw: If you drink a cold or acidic beverage, a straw can help reduce contact with your teeth, limiting potential discomfort.
5.Maintain Good Oral Hygiene: Brushing your teeth at least twice a day and using dental floss can help keep your teeth healthy and less susceptible to sensitivity.
Managing Sensitivity After Whitening
If you experience sensitivity in the hours following the application of the whitening product, there are some things you can do:
– Continue using toothpaste for sensitive teeth.
– Avoid extremely cold or hot foods and drinks for a few days.
– Use products based on Potassium Nitrate provided by your dentist.
Conclusion: A Bright Look without Discomfort
Tooth sensitivity can be a side effect of teeth whitening, but with the right preventative precautions, it’s possible to achieve a whiter smile without particular discomforts. As always, the key is to work together with your dentist, an expert in cosmetic dentistry, to find the most suitable treatment for you.
