Brief answer...given below Detailed answer... Hello, Thanks for the query. Although the chances of developing osteonecrosis of jaw following a dental work in people taking alendroate is very less and is rare,but the guidelines suggest that anybody taking the alendroate for less than 3 years can stop the medicine 3-4 weeks prior to the surgery,while a person who has taken alendroate for more than 3 years should discontinue the alendroate 3 months before dental surgery. For you a period of maximum 4 weeks is more than enough to be on safe side. I hope it helps however you may revert to me for any further query. Best of luck Thanks
