Q:

Hi Dr. Toof, I hope you’re doing well! I’m a 35-year-old father, and I’ve been noticing that my teeth have been getting yellow even though I brush them twice a day, like I’ve always been told to do. I eat a pretty balanced diet, and I’m careful with sugary foods, but I still can’t figure out why this is happening. My teenage son is also starting to worry about his teeth, as his friends have commented on their color too. I’d really appreciate your advice on why our teeth might be yellow despite regular brushing and what we can do to improve their color. Thanks so much!

Hey there! Thanks for reaching out and it’s great to hear that you’re keen on keeping your teeth healthy. First off, even if you’re brushing regularly, there are a few reasons why your teeth might still appear yellow. Genetics do play a part—some people just naturally have a slightly yellower shading. Also, if you’re a coffee or tea lover, these drinks can stick to your teeth and add to the yellowing. Don’t forget as we age, our enamel—the outer layer that’s super white—wears down, showing more of the yellowish dentin underneath.

Now for some quick fixes you might want to try while you work on a more long-term plan. Whitening toothpastes can be your friend as they help lift surface stains. You can also try rinsing out your mouth with water after you enjoy your favorite staining drinks or foods. Cutting back on things like tea, coffee, or even dark sauces could make a difference over time.

When it comes to more permanent solutions, visiting your dentist could be the way to go. Professional whitening treatments can be far more effective and longer-lasting than those DIY kits you find in stores. Plus, it gives your dentist a chance to see if there are any other issues, like enamel erosion, that might be affecting the color of your teeth.

Don’t forget how important regular dental check-ups are. Since both you and your son are noticing changes, it’s a good idea to get some expert advice. Your dentist can give personalized recommendations that are both safe and effective, helping both of you maintain good dental health.

And remember, here in Malaysia, we place a lot of value on health. It’s a great chance for you to show your son the importance of taking care of himself. Making dental check-ups a family routine not only keeps you both smiling brightly but also teaches healthy habits that last a lifetime!
