Initially, your dental surgeon will conduct a consultation in order to discuss your dental needs. They will also ask for dental X-rays and scans in order to understand the overall conditions of your teeth. Seeing the reports they will also understand whether you are the right candidate for sinus lift or not.
Once, they are confirmed, they will go on with the surgery procedure. It will begin with making an incision in the gum so as to expose the bone lying underneath. After the surgery, you might experience swellings in the area along with bleeding. You might also experience discomfort for a few days. In case the conditions get worse, you should contact your dentist immediately.
