欧博百家乐4 Ways to Get Rid of Yellow Teeth
Teeth whitening strips are generally very safe for patients. I recommend the Crest Whitestrips, which are affordable, safe, and can make your teeth a few shades lighter. Make sure to brush your teeth first before using the strips so that the hydrogen peroxide can penetrate to the enamel better, and avoid eating anything an hour after the treatment for the best effects. You can initially use these strips to get the shade you desire and then use them again the next month as a refresher to maintain the shade.
Whitening strips are not recommended for people with braces or restorative work, such as fillings, veneers, crowns, or dentures. Sometimes the strips can cause sensitivity in gums or teeth, and if that's the case, I would advise to stop using them.
