It is not uncommon to come across people with missing teeth, rotten teeth, or unsightly gaps in their smile. The thing is that this is not always a result of poor dental hygiene. Many people have missing teeth due to sports injuries and accidental impacts. For example, it is not uncommon for a child to knock a tooth on a blunt object and to damage the delicate nerve inside. This nerve may slowly deteriorate over time without the child even knowing until one day as an adult the tooth turns rotten and needs to be removed!
