It is quite common for your teeth to get stained and discoloured with the kind of food habits we take in our day to day life.
That's the reason people tend to spend lots of money on teeth whitening.
Have a talk with your dentist either through a call or visit the office directly.
Have an open chat regarding your dental issues and the best dentist will always help you out.
If you didn't have oral hygiene properly before, your dentist will remain all the stains and plaque which is present over and between your teeth.
Then you will be applied by a whitening gel followed by a laser light will be activated for about 20 minutes which will be repeated for a few times until your stains vanish away.
