Fresh fruits like apple are natural cleanse of your teeth.

Smoking or consuming smokeless tobacco is very harmful for your teeth. It can lead to various oral diseases like oral cancer, gingivitis, periodontitis and tooth decay. 

Hi, there are various reasons of bad breath, like impurities in blood, inefficient digestive system, dry mouth (lack of saliva production), gum disease, cavities, plaque and tartar formation around teeth and gums, kind of diet, improper brushing / cleaning of mouth etc. I would advise you to get a thorough physical and dental examination to rule out the cause of bad breath and to solve it permanently.

Kindly get scaling and polishing done and if you want you can also get bleaching done. Brush your teeth twice daily using correct brushing technique to maintain your oral hygiene.

Brushing baking soda on your teeth twice a month can remove the stains of coffee or red wine and give you your pearly white teeth back.

There are many treatments available for bruxism, including relaxation and awareness techniques. Counselling may help to relieve stress in your life. Improving the quality of your sleep can be of benefit. This may include reducing the use of stimulants such as caffeine and nicotine, having enough sleep, making sure you have a good bedtime routine and relaxing before bed. Treating sleep apnoea in some people may also help to control sleep bruxism. There are no medications that will stop sleep bruxism. A grinding mouthguard can be made. This is like a sports mouthguard, but harder. It will help protect the teeth, muscles and jaw joint from the pressure of clenching and grinding. It will not stop bruxism and in some cases can make the actual grinding worse, but it will lessen the damage to your teeth.

There is no way that front teeth will cause pain in the back of the jaw. Please rephrase the question so that I can answer and help you.

Common cold can cause pain in the upper back teeth. This is because the roots of these teeth are very close to the maxillary sinus which is involved in sinusitis. So, a person suffering from sinusitis can experience tooth pain even in the absence of any problem in the tooth as such.
The usual measures to treat sinusitis are sufficient to help cure the tooth pain in such cases.

If there is pain anytime in that teeth go for rct otherwise simple restoration is required for this.

Some times after removal of braces doctor suggests retainers for another 6 months. Consult the doctor if you need retainers.
