Tooth and Mouth Problems

Hi I am facing a lots of dental problems because of smoking like black teeth and dark gums. I am thinking to go for teeth whitening. Is that a good option and how much will it cost ? What can i do for dark gums? Please reply asap.

There is a dentist in my colony..how do i know that he is a good doctor... whether i should consult him or not

I have just left smoking few weeks ago nw lots of ulcers in my mouth having loads of problem it's paining alot

My daughter having issues with tooth from the age of 2 years.. Now she is 3 years and 9 months. The problem is started like colour change to her 2 upper front tooth. Then it started to decay. Now there is only 1/4 left. Consulted a pediatric dentist that time. He said that its because of lack of proper cleaning. He said to brush 2 times and also to clean thooth with cotton. Also cleaning mouth after whatever she eats. Before it was only found in upper jaw tooth.. But now started showing problems to lower tooth too. I'm very tensed by seeing it.

My bottom 3rd molars are covered by skin and a part of 2nd molars too. My front teeth are inclined. Is there a way to fix it?

My front tooth started decaying and had to undergo root canal treatment,now currently have Ceramic metal cap Fixed ( Don't know the exact name) they replaced the original tooth After 8 years, now my tooth started to lose the alignment...it's giving me pain and swollen gums! When asked I found Zirconia crowns are durable and gives good appearance! Is it true? What's the cost? Any help!

A perforation is suspected. And to examine this there is a need of microscope.it can be treated 100% or not.i am afraid.

I have two gaps between my teeth and upper side is not in order so is there any remedy for this quickly

I frequently  develop mouth  ulcers  after my wisdom teeth removal.  What is the precaution to be taken. I have done rct by 23rd March. Again my next appointment with the dentist for putting the crowns by 12th April.  I do my oil pulling daily can I continue this after rct. Any medications need to be taken?

Suffering from bad breath even after brushing my teeth twice a day. After leaving bed in the morning I brush my teeth and after having meal in night I do brush my teeth again. But the foul smell exists. People are avoiding conversations with me in my office. Any suggestion to overcome this problem would be a great help.
