Everyone wishes to have a bright, pearly white smile that boosts their confidence, and thanks to modern dentistry, it’s more achievable than ever. With in-office teeth whitening treatments, you can have a dramatic smile transformation within a single visit. However, many patients experience that their teeth feel sensitive after the procedure. In this blog, we will discuss why tooth sensitivity happens after whitening, how long it lasts, and the best ways to manage it.
Why Do Teeth Feel Sensitive After Whitening?
Sensitivity after teeth whitening treatment is often a common and temporary side effect. This is because professional treatments involve the use of bleaching agents like hydrogen peroxide or carbamide peroxide to break down stubborn stains on the enamel. During this process, the peroxide can open microscopic pores in the enamel, exposing the inner layers of the tooth.
As a result, your teeth may temporarily feel more sensitive to hot, cold, sweet, or acidic foods and drinks. It is usually short-lasting and subsides within a few days. By carefully following your dentist’s post-treatment instructions, you can reduce discomfort and recover more comfortably.
How Long Does Sensitivity Last After Teeth Whitening?
Most patients experience mild tooth sensitivity after teeth whitening, which may last 24 to 48 hours. In rare cases, this side-effect may last for almost a week. It depends on the health of your teeth, enamel thickness, and the type of whitening solution used.
If you are using over-the-counter teeth whitening kits, be aware that misuse or frequent application can cause prolonged sensitivity. While these kits contain lower concentrations of bleaching agents, they may still cause enamel erosion if not used properly. Professional teeth whitening, on the other hand, is much safer as it is performed by trained dental experts and customized to suit your oral health needs.
Best Ways to Manage Sensitivity After Teeth Whitening
In the majority of cases, sensitivity after teeth whitening is usually mild and resolves on its own within a few days. However, you can avoid this temporary discomfort by following these helpful tips:
- Avoid hot, cold, or acidic foods and beverages for the first 24–48 hours.
- Opt for lukewarm or room-temperature foods and drinks to minimize discomfort.
- Avoid the intake of dark-colored or pigmented foods like coffee, red wine, dark soy sauce, and berries that may stain your teeth.
- Use a desensitizing gel or toothpaste recommended by your dentist to relieve sensitivity.
- When brushing your teeth, use a soft toothbrush and gentle cleaning techniques to avoid irritation.
- Consult your dentist before using any DIY or store-bought teeth whitening products.
To Sum Up
It is completely normal and expected to feel mild tooth sensitivity after teeth whitening. It usually subsides within one to two days, but if it persists for longer than a week, you should seek professional care.
