Tooth and Mouth Problems

Tooth ache since last hour. Unable to sleep Applied clove oil Took combiflam.

My teeth have yellow stains which I intend to remove or whiten. How can it be safely done? What are my options ?

Daughter is 2yrs 5month till b4 10days i was feeding her due to that her front teeth has damaged. What should be done for it ?

I want to discuss the alignment cost, as i have already been seen 3 orthodontist so far, and i want to go with clear aligners, what i got from them is that its extraction case( 4 tooth to be removed). I don't want to use braces from outside. Lingual and clear aligner are the options which cost me (Lingual : 1L and above 2L , clear aligners 1.5L and more than 2.5L(invisalign)). Are these costs standard or it can be optimized like instead of invisalign, clear path etc can be option.

I have a gap in the lower part of front teeth's which can almost fit in a new teeth. Is it possible to add a new teeth in that place and how much does it cost ? Or let me know if there are other ways which can be considered.

No 4 tooth on top is having cavity and filling was done now it is removed plus consulted many doctors; need to do Root Canal Treatment on it; but there has been pretty costly in Bengaluru. Please suggest some doctors who do it for lesser price or discounts

If I go for an root canal whether it will pain more or teeth extraction will be. If filling is done with composite material for how long it will exists and what precautions I need to take

My tooth has decayed and gums have covered the cavity. I have cavity and  decay in other teeth too. Please help what to do
