Based on your info, i guess it is from 3rd molar/ wisdom teeth. People around this age usually have this kind of problem. The wisdom teeth is erupting, and it will be uncomfortable. If it is due to wisdom teeth, i will usually ask the patient to bear with the pain and let it erupt, the pain can be control by taking pain killer, and also to take care the oral hygiene by gargling with water after each meal. Note that there is a chance the tooth is tilted and no chance for it to erupt, if the tilted wisdom teeth giving pain, extraction is the only way.

Impacted 3rd molar

For bad breath, try
1) Brush your tongue
2) Avoid strong smell food, like garlic and onion
3) If your teeth have cavity, food may get stuck inside and hard to get out, hence the smell
4) Drink lot of water
5) Do flossing and interdental brushing, sometime food may get stuck in between teeth and its hard to get it out by brushing alone
6) Chew sugar-free gum ( temporarily measure )
7) Go for dental check up, maybe you have abscess that you didnt notice, or its time for you to do scaling. A thick calculus can often produce unpleasant smell

Hope this help

I guess your daughter now is about 6 years old. If there is no obstruction in front of tooth, it will be straighten it back naturally. Give it a time of 3-6 months to observe. But they will not do a braces or appliance on your daughter now as she is still too young.

Hi,

I've not undergone any braces treatment myself but I'm a dentist so I guess I can give some advice.

1. Cleanliness is everything, it might be hard but your orthodontist/dentist should explain about methods of brushing when having braces on.

2. Try not to eat hard or sticky food as this may cause dislodgement of brackets.

3. In any case bracket Is dislodged try to get an appointment as early as possible as that may cause unwanted changes in tooth movement.

4. Slight pain or tenderness is normal, ulcerations are normal, you can request for orthodontic waxes to be put on the brackets to prevent the ulcerations.

5. Try to minimise heavy staining drinks such as coffee or soft drinks as they may accelerate staining on the teeth.

That's all I can think off for now, if you have specific questions I'll be more than happy to answer.

Calculus form very easily with braces on, because food stuck easily (sometimes even without you realizing until you see the mirror).
