Question: Hello, when my mouth is at rest (closed), my upper and lower teeth do not touch each other. Its like they are aligned with a space of 1mm. If i try to bring my lower jaw in, for the lower teeth to touch the inside of upper teeth, my face looks really awful.. Is it normal that the teeth dun XXXXXXX at rested position..I do not have any pain in the teeth or jaw.. and during eating my teeth touch each other.

Thanks for writing to us,
I am glad to inform you that it is absolutely normal to have a space(less than 4mm) between your upper and lower teeth at a rest position.
In fact, if the teeth XXXXXXX at rest position, it is a painful condition.
There is nothing to be concerned about,
I hope this answer was useful,
If you have any further queries for me , kindly write back,
I wish you good health.
Take care.

Thanks for your reply. I am glad to know that its normal.
Just wanted to provide some more information to be sure.
I once visited a dentist and he said that the way i close my mouth is incorrect. He said that the mouth should be closed in such a way that the lower teeth should be behind the upper teeth which is how most people have and that's not the case with me. My lower teeth is below the upper teeth.

I tried to bring my lower jaw a bit inside so that the lower teeth is inside but the face looked really weird.

Please let me know if its still normal.

Hello sir,
Thanks for writing back,
I would like you to know that we classify the alignment of teeth into 3 classes.Approximately, 50% of the population has class I , about 30% has a class II and the remaining have class III.
And whatever history you give suggests a class III occlusion.
There is nothing abnormal ,
In some cases we need to correct it with surgery or orthodontic treatment.
But if its not bothering you then there you should not be concerned..
In all probability, one of your parents must have had such an occlusion from where you got it, but you don't have to worry at all, its absolutely normal.
I hope I answered your query.
I wish you good health.
Take care.

I have periodic pain in my left lower jaw. Like a cramp. It is pronounced when I turn certain ways. I have a malocclusion so thought it may be a TMJ issue ( a known risk ) but I don't have "clicking" and no pain when eating. What might it be ?

When I chew food I get a minor tingling in the back of my head adjacent to my ears.This started shortly after I had some fillings done at my dentist .

My daughter is 12 years old. She has underbite of her incisors. When to start treatment? Is palatal expansion required? Her right lateral incisor is erupting and is now behind the row of teeth.

Hello, I have an orthognathic surgery on both jaws for under-bite correction in 2006. Every now and then, I have tingling sensation in my lower chin which reduced over time. Some time I experienced pain in my right side teeth in upper and lower jaws. Recently (almost 8 years after surgery), I have consistent pain mainly in upper jaw and sometime in lower jaw. The pain is very random but sort of continuous. It seems to originate near to one of the teeth (number-2) which I noted have Titanium plate near its upper root. Initially, I though it might be root infection but dentist find all teeth healthy although he told me he have to perform 3D X-ray to check the portion of tooth root behind the Ti plate but he told me like hood of root damage is low to nil. Do you have any idea of what might be causing the pain ? I though the nerve, muscle, tissues, bones would have generated by now. I did not have any accident recently but as I mention this kind of sensation arises before (for short timings/a day or so) after I was recovering from operation. However recently, It have stayed for more than 4 days and still continue. The pain is radiating from under right side of nose with right check near molar with bit tingling feeling. Thanks for your advice.

okay, so i have a rather specific question regarding orthognathic surgery...hope u can be of help. i have a bit of an underbite and will probably have corrective jaw surgery in a couple of years to fix it. i also have a rather long-shaped head. my question is: will fixing my underbite make my head look a little smaller?

I have a 7 yr old daughter with underbite a little over a 1/2 from top teeth, our dentist is advising us to see a orthodontist for surgery to break her jaw, we are very concerned. I don t want my childs jaw broke, we went today and was told they would need to break her jaw, we thought we were going to possibly speak of having braces put on, what are the pros and cons if we decide to do this. I want more than 1 opinion on doing this.

Hi,My teeth are all straight except that I have a overbite,and a gap in my front two teeth(I used to suck my thumb when I was little)I went to a dentist and he told me I would get a retainer to pull the front teeth together and move them inwards to get rid of the overbite and spacing,But the issue I have is that the underbite causes my face to look shorter,when I move my lower jaw outwards to get closer to my upper teeth my face looks much better,Does an overbite mean that my jaw are not align correctly?I d like to know if braces can actually move my lower jaw outward rather than moving my upper teeth inward or is there any other option that can do that, Im a 20 year old female am I too old to have my jaw align since I dont think its growing anymore?
