Some people develop a third set of molars and others don’t. The “wisdom teeth” may come in inappropriately and will require treatment.
A cyst may form if a wisdom tooth becomes infected and you may notice swelling around your gums and cheeks. If a wisdom tooth starts to come in at an awkward position contact your dentist.
Xrays will allow your dentist to observe the alignment of the molars.
No treatment is necessary if your wisdom teeth have plenty of room to emerge correctly, but if they become problematic extraction may be advised.
