➺ Smoking is one of the main causes. Smoking leads to small black deposits on teeth, which appear as black spots. These spots appear due to the already present calculus and tartar on the teeth. Often, smokers are not able to maintain good oral hygiene, which only further worsens the condition of their teeth.
➺ The treatment will depend on the underlying cause of the discoloration. If these black spots are extrinsic in nature, like if they are caused due to smoking or tobacco chewing, then the only treatment option is to get the teeth cleaned, by getting an ultrasonic cleaning done, by a certified dental hygienist. The cleaning will remove the stains that are present on the surface of the teeth.
