We all want to keep our smiles looking bright as we head into our fifties and beyond. It’s natural for teeth to yellow slightly over time, and the temptation to grab a box of whitening strips from the pharmacy is very real. However, one of the most common mistakes I see among our age group is trying to whiten dental work like crowns, veneers, or composite fillings using over-the-counter products.
The reality is that the materials used for crowns and bridges are non-porous. Unlike our natural tooth enamel, these materials do not respond to peroxide or abrasive whitening agents. If you apply a strong whitening treatment, your natural teeth will lighten, but your dental work will stay exactly the same shade. This often results in a “patchwork” smile where your crowns look much darker or yellower than the surrounding teeth, which is usually the opposite of the look you were going for.
Instead of reaching for those strips, a better alternative is to schedule a professional cleaning. A hygienist can often remove surface stains from porcelain that home brushing misses. If your crowns are truly looking dull or the color no longer matches your aging teeth, it might be time to discuss replacing them with your dentist. They can match the new crown to your lightened natural teeth for a seamless look. Also, focusing on high-quality gum care can make your teeth appear healthier and more vibrant without the risk of uneven whitening. It’s all about working with the dental history you have rather than fighting against it.
