When I was younger I did not maintain my teeth well. I am now in my early 20’s and have since realized the impact of oral hygiene and now have a good routine. However because of my lack of hygiene as a child my teeth are very yellow, noticeably yellow. It cause me so much embarrassment now and makes me never want to smile. I would really like to get my teeth whitened professionally but I have a few questions..

1. How much does it usually cost (if it varies too much depending on location disregard)

2. Is there a point where teeth are too yellow and won’t whiten?

3. Will I have to get my fillings replaced? Thank you in advance!
