Host: Dr. Yu, everyone wants that "Hollywood smile," but there are so many products out there. How do you help your patients at Your Nashua Dentist get a brighter smile safely?
Dr. Yu: It’s all about the professional approach. Teeth whitening is more than just applying a gel. At office, we can seal the gel inside root canal treated teeth and whiten discolored tooth resulting from nerve damage. At home, you can apply whiting gel to custom-made trays to ensure the best results. Finally, there is a specialized formula that is activated by lights to break down deep stains on the enamel. My background in medical research at Eli Lilly makes me very focused on the science behind it—we take extra precautions to protect your gums and manage any sensitivity concerns so the process is completely comfortable.

Host: Why is it better to see a dentist for this rather than just using a kit from the store?
Dr. Yu: Because we start with a Dental Health Assessment. Not all discoloration is the same; some stains are on the surface, while others are deeper. We tailor the whitening method to your specific needs. It’s also important to make sure your teeth and gums are healthy enough for the procedure first. At Your Nashua Dentist, we want your results to be safe, effective, and natural-looking.

Host: And how long can a patient expect that bright, white look to stay?
Dr. Yu: It can last anywhere from six months up to three years, depending on your habits. If you’re a coffee lover or enjoy red wine or deeper staining like tetracycline staining, the effects might fade a bit sooner. We always tell our patients that the best way to maintain that glow is through good oral hygiene—regular brushing, flossing, and routine check-ups and catch-up whiting in our office.
Host: It sounds like a great way to boost confidence before a big event like a wedding or a job interview.
Dr. Yu: Exactly. Seeing that instant transformation is one of the most rewarding parts of my job. We want our Nashua neighbors to feel proud every time they laugh or smile.
