I'm worried as i've had a lot of anesthesia over the past month to do fillings in my mouth. will there be any negative effects?

No: Your dentist probably used local anesthetic to do the fillings. The doses that they have been using are not cumulative, unless they were all injected at once. Your body easily removes these medications, which is why the numbness wears off. There will be no long term effects.

No worries: As dr. Pollard has answered, there should be no cumulative effects of local anesthetics. Additionally, nitrous oxide anxiolysis, or even IV sedation, if any of these were used, were used will also not have a bio-accumulative affect. They are metabolized and excreted.
