Why Are My Teeth Still Yellow After Trying Brite Smile Teeth Whitening?

I’ve been dealing with yellowish teeth for a while, and regular whitening products haven’t given me the results I expected. I’m considering brite smile teeth whitening because I want a brighter smile without making my teeth feel sensitive. I’m also curious whether dental implant specials are available for people who may need implants along with cosmetic dental work. I came across Smile Design 101 and Dr. Kosmas Kasimatis while researching options. I’d appreciate honest experiences, practical advice, and tips on choosing the right treatment.
