Wisdom teeth all you need to know about them.
- These are the last molars on each side of the jaw, both upper and lower
- There are total of 4 wisdom teeth in each person, however this varies from person to person and patients may have anywhere between none to 4
- These teeth may erupt and are visible in the mouth or they may continue to be present inside the gums or bone and are not visible in the mouth.
- The normal age of eruption of these molars is 17-21, however they may erupt beyond 21 years of age
- Wisdom teeth are impacted most often due to the size of the jaws, in smaller jaws there is a greater probability the wisdom teeth will be impacted
- It is advised by American Dental Association to have one check up to evaluate all your wisdom teeth. The dentist may advise removal of these molars.
- Wisdom teeth are removed for the following reasons
- Wisdom teeth can develop cavities
- Wisdom teeth that are not fully erupted and angulated may put pressure on neighboring teeth and damage them
- They may develop and progress into pathological conditions like cysts
- Third molars and wisdom teeth are generally removed by experienced dentist who are confidant to remove wisdom teeth or by qualified specialists in Oral and Maxillofacial surgery.
- General anesthesia can be used to remove the wisdom teeth. The cost of the removal of the teeth will increase under General Anesthesia
Investigations or tests
- A single radiograph is required for surgical extraction of teeth other than the third molars. The dentist may also request a Orthopantomogram (Full Mouth X-ray) instead
- An Orthopantomogram is required for impacted teeth
- Blood investigations may be desired based upon the past and existing medical history you provide to the doctor
Why is Medical History important to be disclosed to the Dentist?
- Medicines that we take for some medical conditions can delay the healing and cause bleeding from the area where the tooth has been removed. Example: Aspirin for heart disease.
- Presence of medical conditions can delay healing, the patient may go into fits (seizures if he has epilepsy), damage the organs of the body if he has heart disease and if proper precautions and appropriate medicines are not taken before and after the removal of the tooth.
- Allergic reactions can take place if medical history of allergy is not shared with the doctor
- Patients with medical conditions or on certain medications are predisposing factors for patients going into unconsciousness during the dental procedures. The dentist will have to take adequate precautions prior to initiation of the procedure in such instances.
Procedure
- A gel is applied to the gums prior to use of the injections to anaesthetize the area
- The dentist will need to expose the gum over the bone to gain access to the tooth
- If the tooth is inside the bone, the dentist will have to further expose the bone to gain access to the tooth.
- Once the tooth is visible, the dentist may split the tooth into two or more pieces for ease of removal
- The tooth is then removed
- Once the tooth is removed, the dentist will clean the area from where the tooth was removed and will put in a stich to allow the gums to cover the area.
- Stitching the gums will help in the healing process
- A cotton or gauze pack is placed over the area from where the tooth was removed
- A follow up checkup is advised after 5 days from the date of the extraction. If stiches were placed it would have to be removed after 5-7 days, depending upon the advice of the dentist
