If your stained teeth are bothering you, then you may want to get rid of them as soon as possible. You deserve a confident smile after all, so you may undergo a whitening treatment. However, before you get a professional service or use an over-the-counter product, you should visit your dentist for a consultation. This will help ensure you have no cavities that get in the way of your results. Here’s how this oral health issue can cause problems for your soon-to-be confident grin.

Why Don’t Cavities and Teeth Whitening Mix?

Teeth whitening works because of bleaching agents. They break down dark particles on and within your enamel, effectively brightening it in the end. This process is meant to be pain-free, but a cavity makes it a more uncomfortable experience.

When you have decay, it may be exposing your dentin. This is the second layer right underneath your enamel. It has tiny channels that help your teeth feel things like temperature and pressure. However, whitening products can trigger sensitivity instead. You’ll be dealing with this discomfort instead of enjoying your results.

Thankfully, you can avoid this by getting a consultation from your dentist. They will make sure there are no underlying dental problems that can get in the way, and your enamel is strong and healthy.

What Is It Like Getting Professional Teeth Whitening?

After you visit your provider to make sure your mouth is a good foundation, they can then offer you the whitening treatments they have. You’ll talk about the goals you have, then they’ll customize the service to you.

One reliable option you have is an in-office visit. Your dentist will apply a professional-grade bleaching gel and then put a specialized light on your teeth. It typically takes about an hour, but you can get up to a 10-shade difference. If you want a more convenient option, then a take-home kit can be right for you. Here, you’ll apply a high-grade gel to customized trays and wear them for a specified amount of time every day for a couple of weeks. This will also give you similar results.

These treatments are both effective and much safer than store-bought products. Your provider will help ensure your enamel stays strong in the end; that way, you just have to focus on showing off a smile you love.
