The optimal age to begin orthodontic treatment is typically 7 to 9 years old. This is because at this time children have a combination of adult and baby teeth, making it easier to fix problems like crowding or an improper bite. Early intervention can prevent more severe issues as they get older. If your child has irregular teeth, difficulty biting or chewing food, or breathes through their mouth regularly, then seeing an orthodontist for assessment would be wise. 

You may have halitosis, which is the scientific name for the condition we commonly refer to as bad breath. Even though you properly care for your oral hygiene, bad breath may still occur. This may be because of the kinds of food you eat, dry mouth, or the leftover food particles stuck inside your mouth. If you want to solve this challenge, practice drinking more water, chewing sugar-free gums, and crunchy veggies and fruits.

SWELLING in one gum with slight pain could indicate: - Canker sore - Gum infection - Abscess - Gum disease. Consult a dentist immediately to avoid complications.

In a situation where your gums are receding, you must visit a periodontist to discover the leading cause of the problem. After solving the main cause, your doctor may discuss implants as a solution for you. 

You can protect the enamel by cutting off sugary diet, limiting the use of fruit juices and stopping having aerated drinks.

It sounds like your teeth are going back to their original positions again. This is possible to happen in the case that you do not use your retainers according to the plan of your orthodontist. The deletion of the braces, and retainers are useful for keeping teeth in their new position. They are the ones responsible for the extraction of teeth which in turn migrate back. The first and the most important step to stop it would be to rank shifting to acutely wearing the retainer again. Be relaxed, talk to your orthodontist, and ask for instructions.
