Do you suffer from repeated dental decay that resulted in numerous dental treatments? At Smile Dental Clinics, we do everything we can to save your natural teeth. We may recommend a filling or root canal to save a tooth. Once all options have been exhausted, the decay has spread too deeply under the gumline, severe gum disease is present, or an infection cannot be healed we might recommend a tooth extraction. A tooth extraction is the process of removing the entire tooth and tooth root.
