How to pull your own wisdom tooth

Wisdom teeth, also known as third molars, are the last set of permanent teeth to erupt, usually between the ages of 18 and 21. Although known as the “wisdom teeth”, these teeth are unfortunately not very smart; because of their tendency to grow in the wrong direction, they become impacted and cause a lot of problems in the process.

In recent years, it has been observed that more and more young adults are presenting with at least one impacted wisdom tooth, and although the exact cause is not known, it has been speculated that our modern diet has resulted in smaller jaws which cannot accommodate all our teeth. Consequently, the wisdom teeth do not have enough space to erupt properly and will become impacted. In Singapore, one study showed that almost 70% young adults between the ages of 20 and 40 have at least one impacted wisdom tooth1.

To Remove or Not To Remove? That Is the Question

It’s always best to see a dentist for an examination first before deciding if your wisdom teeth need removal. Radiographs or X-rays are also necessary as sometimes the wisdom teeth lie just beneath the gums and cannot be seen in the mouth.

If you are one of those lucky few whose wisdom teeth are all fully erupted and at the correct angulation, then there is no need for you to have any of them removed unless they are decayed or difficult to maintain.

Fully-erupted wisdom teeth which do not require removal.

If your wisdom tooth is deeply buried (fully encased in bone), it may not be necessary to remove it since it will not cause food trapping (which leads to gum infection and decay). However, due to its potential to turn into a cyst (an expanding fluid-filled pathology which erodes into the neighbouring bone and teeth), it is recommended that the tooth be monitored with regular X-rays.

If your wisdom tooth is partially erupted, it will remain so and is at high risk of developing symptoms; hence, it is recommended that you have it removed sooner rather than wait for it to become painful.

Should you remove problematic wisdom teeth before having any symptoms such as pain and swelling?

Yes, you should! Waiting for the wisdom teeth to start bothering you is actually not a good idea. There are two very good reasons to justify prophylactic removal of wisdom teeth:

Impacted wisdom tooth which traps food and should be removed as soon as possible.

Should you decide to remove a lower impacted wisdom tooth, we sometimes recommend that you remove the upper wisdom tooth at the same time, even if it is not impacted, as leaving it will allow it to over-erupt and it will come into contact with the lower gums when you bite, leading to ulcers, cheek biting and pain. Also, the tooth is non-functional since it does not have an opposing tooth and may be challenging to clean.

Upper wisdom tooth which is not impacted but is causing pain by impinging on the lower gums.

Removal under Local Anaesthesia vs General Anaesthesia

Most wisdom teeth surgery can be done under local anaesthesia. This means a chair-side procedure where the surgical area is first numbed up and the tooth removed while the patient is awake. After the surgery, the patient does not need to be accompanied home as there are no drowsy side-effects. If you are having the lower wisdom tooth removed under local anaesthesia, you can consider removing the upper wisdom tooth at the same time. That way, you can still chew on the unaffected side while you recover.

However, if you have 2 to 4 impacted wisdom teeth and you are very nervous about the surgery, you can opt for general anaesthesia, where you will be put to sleep for the entire duration of the surgery (technically, one is not asleep during general anaesthesia but unconscious). However, you can only have this done at facilities equipped with life support and resuscitation devices, and that would mainly be at hospitals. Additionally, be prepared to pay an additional $800 to $1000 on top of the surgical fees, in order to cover for the anaesthetist and operating theatre fees; you will also need to be accompanied home as you will be suffering from drowsiness and sometime nausea after the surgery.

Generally speaking, normally only 1 to 2 wisdom teeth on the same side is removed under local anaesthesia, whereas under general anaesthesia, all wisdom teeth should be removed at the same time. So do expect a longer downtime of around 8 days of medical leave after general anaesthesia, as opposed to 5 to 7 days medical leave for local anaesthesia, and a longer period on a soft diet as both sides would be sore and swollen after the surgery.

Can I Utilise Medisave for Wisdom Tooth Surgery?

If your wisdom tooth is fully erupted and can be removed without any surgical intervention, then this is considered an extraction and you cannot use your Medisave funds to pay for the extraction.

However, if your wisdom tooth is not fully-erupted, or is positioned underneath the gum or in the wrong direction (considered impacted), where surgery is required to expose the tooth completely and to remove the tooth, then yes, you may utilise your Medisave funds (or that of your spouse’s, parent’s, child’s or sibling’s, with their consent) to pay for the surgery, as well as any medications, consumables and radiographs taken on the day of the surgery.
