Can laser cavity removal hurt?

Probably not: I hope that this question relates to dentistry. When lasers are used in dentistry they should only be used for specific situations. If used in the correct manner the laser should not cause much sensitivity.

Usually no: One of the benefits of using a laser is usually you don't need any local anesthetic for cavity removal. However, sometimes if the cavity is very deep, you might need some anesthetic. Patient variability in pain thresholds are also important and need to be considered. You might start the procedure without anesthetic, but as it progresses, if you need anesthetic, the doctor can give you some.

No: It is very safe and painless.

Dr Ali agreed

Mimimal: Laser cavity removal only works on virgin teeth some patient feel it more than others.

Dr Ali and another doctor agreed

Depends on severity: The bigger the cavity, the closer the infected tooth tissue is to the nerve of the tooth, the greater the risk for discomfort. Your dentist is skilled in anesthesia and in selecting the best decay removal mechanism. Talk it over with your dentist.
