The need for whitening.
Even though a person has good hygiene and keeps their teeth clean, nevertheless from the things one eats, or drinks, like coffee, coke, tea, wine, etc., and/or the use of tobacco products, your teeth can get stained. Yellow stained teeth look terrible. The thing is, brushing just doesn’t remove the stains, and too much brushing can cause gun recession. That is why many patients come to the dentist to get a cleaning, and a whitening.
