Many people do not visit dentist regularly because they feel that they do not need to. But did you know that there could be underlying problems that cannot be seen with the human eye. With regular check-up, the dentist can examine and locate dental concerns that may seem little now, but become a bigger problem in the future. For example, a small filling may develop into a root canal treatment, or even a loss of a tooth (extraction) if the damage is irreversible.
