One of the first things others notice about you is the quality of your smile, and if yours looks more brown or yellow than pearly white, you might not make a good impression. You may already know that teeth whitening can brighten your grin, but if you try over-the-counter options, you might not achieve the desired results. Unfortunately, some people then overapply the product to lighten their enamel, only to develop sensitivity or other concerns.

How Does Teeth Whitening Work?

Although the quality and results can vary significantly, store-bought and professional teeth-whitening products function similarly. Most of them contain a bleaching agent, usually hydrogen peroxide or carbamide peroxide, which has a chemical reaction when it comes into contact with your enamel. The whitener undergoes an oxidation process that breaks down pigmented particles, reducing their size and concentration. This is what lightens the surface of your teeth to improve your appearance and boost your confidence.

Can Teeth Whitening Harm My Smile?

This treatment is usually considered a non-invasive cosmetic service that doesn’t hurt, but it does have the potential to cause sensitivity. When the bleach interacts with our enamel, it expands the microscopic pores there, allowing sensations to travel more easily through the lower layer of dentin and into the roots inside. If you don’t see the desired results and apply more product too soon, you could develop worsening soreness, especially if some of the harsh chemicals touch your gums.  

Not only that, but if you opt for over-the-counter solutions, you might accidentally place bleach over a hidden cavity or gum disease you were unaware of, which can cause intense discomfort. As a result, it’s usually recommended that you have a dental exam before pursuing teeth whitening.

How Can I Avoid Issues from Teeth Whitening?

Waiting a couple of weeks in between applications can reduce the likelihood of developing sensitivity or other concerns. Another simple and effective way to safeguard your dental health while enhancing your smile is to have your teeth professionally treated. Store-bought options often contain diluted bleaches and one-size-fits-all trays with plenty of room for error. Meanwhile, your dentist can provide a take-home kit with ultra-concentrated gels designed to mitigate potential problems after examining your mouth to ensure no cavities or gum disease interfere.

If you prefer more immediate results, you can schedule an in-office whitening procedure that can potentially brighten your grin by up to eight shades in a single, hour-long visit!
