Hello doctor,

My front two teeth are not fixed and have broken edges because of a car accident, but right now I feel like my lower front tooth are peeling. I can feel a white powder type thing whenever I touch the tooth with my tongue. I cannot bite from my upper front tooth plus after the trauma I could not take care of them properly because I feel too much pain whenever I brush. I need your help. Please guide me on what to do? How can I fix my problem? I am very much tensed.



Welcome to

I understand your concern and have gone through your clinical picture. (attachment removed to protect patient identity).

Please do not be tensed. This can be treated.

White powder substance in your lower front tooth is called calculus. Food deposits or plaque that settles on the tooth gets calcified in the long run and becomes hardened calculus deposit. Although we do a proper brushing every day, there are certain spots between teeth where the bristles fail to reach. Hence, professional tooth cleaning (scaling and polishing) is always advised once in six months.

Broken and irregular edges of your upper tooth can be fixed with a simple tooth colored aesthetic filling. Pain during brushing in the lower tooth could be from the impact and damage caused during the accident. Get an x-ray taken to check the status of tooth, gums and its underlying bone and ligament.

Blacks spots on the teeth are the initial stages of tooth decay. Get them filled at once before it advances and gives you pain.

Visit your nearest dentist and get a dental examination done. You will require:

1. Scaling and polishing procedure to remove calculus.

2. Composite fillings for an upper front tooth and lower left back molar.

3. X-ray for your lower front tooth to check its health and stability.

I hope this helps.
