Teeth whitening treatments are one of the most popular dental cosmetic procedures, but often result in tooth sensitivity for many patients. Whether you are a first-time teeth whitener or have done it before, this sensitivity can be a real barrier to overcome. Fortunately, there are some practical ways to manage the problem, which means you can enjoy the benefits of a whiter smile without discomfort.

Tooth sensitivity following whitening occurs because of the bleaching agents that are in the products. Such ingredients, including hydrogen peroxide, can make the enamel temporarily more porous, which may be associated with heightened sensitivity. While this sensitivity is normally temporary, it can make the experience less than ideal.

Let’s explore how to manage tooth sensitivity after teeth whitening and the steps you can take to alleviate it.

Use a Toothpaste Made for Sensitive Teeth

One of the easiest ways to cope with tooth sensitivity after teeth whitening is by using a sensitive teeth-friendly toothpaste. These toothpastes contain compounds that help to soothe the nerve endings in your teeth and protect them from external stimuli. Look for fluoride and potassium nitrate, as these are known ingredients for reducing tooth sensitivity.

For best results, start using this toothpaste a few days before your whitening treatment and continue afterwards. That way, your teeth will be in a more comfortable state once you undergo the whitening procedure.

Take a break between whitening sessions

If using an at-home whitening kit, it is not advisable to overdo it. Frequent whitening also worsens the sensitivity of the teeth. In cases of discomfort during or after a session, one can take some time out before proceeding with another treatment, giving the enamel time to recover and avoid further irritation.

You must follow the advice of your San Jose dentist to minimize the risk of tooth sensitivity. Your dentist may recommend spreading out your whitening sessions to avoid sensitivity.

Avoid Hot and Cold Foods Right After Whitening

Avoid consuming both hot and cold foods for a couple of hours after teeth whitening. Immediately following the treatment, your teeth are more sensitive to temperature changes, and they may cause discomfort with foods such as ice cream, hot coffee, or soup. Only lukewarm foods should be considered until your sensitivity subsides.

Use a Desensitizing Gel

Other great options for sensitivity relief include desensitizing gels. These gels work by temporarily blocking the nerve pathways in your teeth to offer relief. You can apply the gel directly to your teeth following whitening to reduce sensitivity. While many of these gels are available over the counter, for a more professional-grade option, consult with your dentist.

These gels are applied in a layer over the enamel, making them most helpful after treatments taken at home. Follow the instructions for the application to achieve the best results.

Hydrate Well and Rinse With Water

Hydration is key to overall oral health, and it can also help manage tooth sensitivity after teeth whitening. After whitening, rinse your mouth with water in order to help remove any residual bleaching agents. Drinking plenty of water throughout the day will also keep your mouth moist, preventing any further irritation.

Consult Your Dentist If Sensitivity Persists

If the sensitivity persists after these recommendations, it may be time to visit a dentist in San Jose. Persistent sensitivity can indicate dental troubles that require your dentist’s attention. Your dentist can help you determine whether your sensitivity is due to the whitening process or if there is another cause, such as a cavity or gum recession.

In such a situation, the dentist may recommend a special treatment plan for long-term sensitivity management that may include varnishes containing fluoride or custom-fitted trays for desensitization.

Managing sensitivity following tooth whitening need not be a tough job. You can ease the discomfort by using sensitive toothpaste, taking breaks between treatments, and avoiding extreme temperatures. In case of persistence of sensitivity, consult Almaden Valley Smile Design for professional advice and care.
