Q:

Hi Dr. Toof, I’m a 45-year-old mother and I’ve been thinking about teeth whitening, especially since I’ve noticed my smile isn’t as bright as it used to be. However, I’m really concerned about the safety of teeth whitening products, particularly for people with sensitive teeth. I have a few friends who have tried it but ended up feeling discomfort, and I want to make sure it’s safe for me before considering it myself. Also, my teenage kids are starting to worry about their own smiles, so I’d love to know if teeth whitening is safe for them too. Can you share your thoughts on this? Thank you!

Hello there! It’s great that you’re considering enhancing your smile, but I totally understand your concerns about sensitivity. Teeth sensitivity can happen for a few reasons, like worn enamel, receding gums, or cavities. When it comes to teeth whitening, the products usually contain ingredients like hydrogen peroxide, which can get into the tooth and bother the nerve, making sensitive teeth even more sensitive. So, it’s really important to chat with your dentist to gauge how sensitive your teeth are before jumping into whitening.

Having a discussion with your dentist isn’t just a formality, especially when sensitivity is a concern. Your dentist can offer invaluable advice tailored to your specific needs and those of your children. They can evaluate your oral health and suggest whitening methods that are safe and effective for you and your teenagers. It’s also an opportunity to explore alternatives that could be a better fit.

If sensitivity is a factor, dentists often recommend whitening products with lower levels of active substances. Alternatively, professional treatments specially designed to minimize sensitivity could be the way to go. Additionally, there are toothpaste and treatments out there that can help reduce sensitivity by strengthening tooth enamel—these can be used before and during any whitening treatment.

In the meantime, practicing good oral care at home can make a difference in managing sensitivity. Using toothpaste made for sensitive teeth, avoiding very hot or cold foods, and cutting back on acidic meals can help lessen irritation. A fluoride mouth rinse might also be beneficial, as it works to strengthen your tooth enamel and guard against sensitivity.

My advice? Don’t underestimate the power of seeing your dentist to address any discomfort or questions, especially regarding whitening treatments. It’s about keeping your smile healthy and comfortable, not just getting it brighter. Your dentist can guide you safely and help maintain that confident smile for you and your kids. Remember, taking care of your dental health is the best investment for a brighter, happier smile for everyone in your family!
