Hi Vivienne.
Dennis is spot on here. I too could find no reason for any special treatment when on Byetta and undergoing Dental work. However the information below applies if you are on any medication which might have a Hypoglycaemic effect or are prone to Hypo's.
Here is some information about Dentistry which specifically mentions Insulin users which is more related to the risk of infections in Diabetic Patients . Take a look.

Here is a small extract (pardon the pun
)
If you have a dental infection, and require either a root canal or need to have a tooth removed, there are some important things for you to remember. Make sure you eat your normal breakfast before you go to the dentist. If you are taking insulin, take your normal dosage unless your dentist and physician have agreed to alter the dosage. If you have not eaten and are in pain, or feel a high degree of stress prior to a dental procedure, this can cause your blood sugar to drop. By eating and taking the proper amount of insulin, you reduce the potentially dangerous complication of hypoglycemia (low blood sugar).
Either way you should notify your Dentist of any medications and take advice from them.
Hope that helps.
Ken.
