Everyone wants a bright, dazzling smile, and teeth whitening is an excellent way to achieve that! But if you have untreated cavities, whitening can be more dangerous than you might think. While whitening treatments are generally safe for healthy teeth, they can cause serious issues when decay is in the mix. Read on to see why whitening and cavities are a risky combination and what you should do before considering treatment.
Increased Sensitivity after Whitening
Teeth whitening products use bleaching agents like hydrogen peroxide or carbamide peroxide to lighten the color of your teeth. When applied to a healthy tooth, these chemicals can safely lift surface stains. However, if you have a cavity—a hole or weakened area in your tooth—these chemicals can penetrate more deeply, reaching the sensitive inner layers of the tooth. This can cause severe pain and discomfort for days after the procedure.
Teeth Whitening May Make Your Cavity Worse
Whitening with an untreated cavity can make the problem worse. The chemicals in whitening products can weaken your tooth structure further, expanding the cavity and making it harder to treat. In extreme cases, this can lead to more invasive procedures like root canals or extractions.
Whitening Can Increase Your Risk of Infection
Untreated cavities leave your teeth vulnerable to bacteria. When whitening chemicals penetrate a cavity, they can create an opening for bacteria to reach the inner layers of your tooth, potentially leading to infection. An infection in a tooth can quickly spread to surrounding areas, causing swelling, pain, and even more serious complications.
What Should I Do if I Want Teeth Whitening with a Cavity?
If you’re considering teeth whitening but you have cavities, it’s critical to see your dentist first. Treating decay before undergoing any whitening procedure will not only protect your oral health but also ensure that the whitening process is more effective and comfortable. Your dentist can examine your teeth, fill any cavities, and set you up for safe and successful results.
Whitening your teeth is a great way to boost your confidence, but it’s important to think about your oral health first! By addressing cavities before starting any cosmetic treatment, you can avoid unnecessary risks and enjoy a brighter, healthier smile.
