Tooth Extraction: you and your dentist may determine that you need a tooth extraction for any number of reasons.Some teeth are extracted because they are severely decayed; others may have advanced periodontal disease, or have broken in a way that cannot be repaired. Other teeth may need removal because they are poorly positioned in the mouth (such as impacted teeth), or in preparation for orthodontic treatment.We will always ensure excellent anaesthesia before we begin any procedure, and we check in with our patients often to confirm an informed and comfortable appointment.
