No matter what, it won't grow any longer. But just losing a small piece of sesame will not cause any short-term or long-term damage to teeth, you can rest assured.

In fact, the biggest harm of unreasonable use of teeth to bite hard objects is "the formation of cracked teeth". In the early stage, there are generally no symptoms and can't be seen by the naked eye, but after a long time, the crown will be separated due to the increase of cracks, which can cause persistent pain. In severe cases, even the whole tooth needs to be pulled out. Therefore, it is strongly recommended that you pay attention to protecting your teeth and don't bite hard objects with your teeth (such as opening beer bottles with your teeth).

You don't have any symptoms at present, but to be on the safe side, you'd better go to a professional dentist to have a check-up to see if there are any cracked teeth. If so, get braces as soon as possible.
