Answer:
b) Untreated decay in "baby" teeth can harm permanent teeth.
Step-by-step explanation:
Milk teeth, although not permanent, may present complications. In the case of caries, for example, many parents think that no treatment is needed as the tooth will fall out, but that is a mistake. When caries are left untreated, bacteria can enter the tooth canal and promote a permanent tooth infection, which is just below. With this, the permanent can be born with some imperfection, such as malformation, lack of a tip or stains.
Apart from these consequences, if there is no treatment, the caries increase and can take the entire tooth - if it is completely decayed, the dentist has nothing to do but extract it. The problem is that when the baby tooth is extracted early, before it softens, it leaves a space that is taken up by the other baby teeth, which move and stop the growth of the perms. As a result, the permanents can become inmates, grow in half or crooked.
For this reason, it is important that Bernie's parents allow him to have a dental treatment even if he has no permanent teeth yet.
