It may be because you don't brush your teeth often. But you might be thinking, i DO brush my teeth twice a day but you have t brush them thoroughly, it my seem a pain but trust me, its worth it. 2 whole minutes. You may be grunting but take my word for it , it is worth it! Also make sure you have a good, well known toothpaste and a decent brush. If your bristles are starting to fray its time for a new brush! So if you do that, you will have healthy teeth!
yes but not hurt your teeth
your teeth might hurt because u have some new ones wanting to come out
no sharks do not hurt themselves with their own teeth because they don't close their mouth fully and the teeth do not touch them
The sugar in the candy can rott your teeth
Yes, baby teeth can hurt, and most of the time will hurt. The reason they hurt is because you are exposing tender gums and you are ripping roots out of the gums.
Teeth aren't bones but it would probably hurt if you broke a tooth
You will have to get braces if your teeth are twisted but you don't have to get them until your 20,30 or 40 years old and your teeth can untwist if you lose all your baby teeth I think.
Who chews staples? Of course they hurt you.
