Crest white strips only whiten the bottom half of my teeth? Crest white strips never fully whiten my teeth it only whitens like half of each tooth. My teeth are pretty straight and I'm pretty sure I'm applying it correctly so how do I prevent this from happening

Respuesta :

After the white strips try the whitening toothpaste and listerine and cut the white strips down to once a week then every so often so they don't look to different when your trying to get them to stay the same color.
