Tooth and Mouth Problems

Please have a look at the attached xray photo of the upper right side teeth in which I'm having minor sensitivity and occasionally feel pain while eating. Gums are healthy. Had a RCT last month for one of the upper tooth on left side. Age 58 years

My teeth is yellowish I don't know why. I have tried everything but Nothing works. I don't wanna go for teeth whitening as I am scared that might be harmful. What needs to be done?

I had my right canine surgically removed which was stuck under my incisors as my right canine is still my birth tooth so it didn't come out. So the surgery was big as they had to remove it and also protect the incisors. After surgery they stitched it and they removed half of the stitches after 10 days and half of them are still not removed. It's been 12 days now and i wanted to know if it's okay to keep stitches for this long.

I am having yellow colour tooth from a long, have been visited many dentist but didn't got the best results. The yellowness of the tooth is from inside not because of the plaque. I got my tooth cleaned by a dentist long back after which my enamel layer got eroded and left the scratch marks on my teeth Recently gaps are developing between my tooth any homecare suggestions will be all thankful

I just want to know why Iam getting pain in my right side molars when I chew hard things.No sensitivity or No pricking pain, but only when I chew hard food.

My teeths have deposited tartar. Can it be removed with home remedies? What can I do to remove tartar from my  teeth?

Does tartar removing process pain ? Is it costly? What steps should be taken after tartar removal to prevent again deposit of tartar?

My lower jaw is not aligned with upper jaw and I may require mandibular expander for correction. Please help me to connect with orthodontist in Agra or in nearby cities that uses expander treatment for their patient. I already visited 4-5 orthodontist in agra but 2 out of them claim that expander uses for only upper jaw and not for lower jaw (is it true?) and rest doesn't use expander procedure as they say it's typical and not always work.
