Bone and sinus treatment

Serving patients throughout East Sussex and Crowborough

When a tooth is lost, the jawbone beneath it shrinks from lack of stimulation and can change the shape of your mouth. Loss of bone can also be caused by gum disease, tooth development defects, trauma, and by previous dental procedures where efforts were not made to restore natural bone.

Before dental implant treatment can begin your dentist will first need to check that there is sufficient bone for an implant to be placed successfully. If there is insufficient bone you may need to have pre-treatment before your dental implants can be placed. This may include oral surgery procedures such as bone grafting, bone expansion or sinus lifts.

At your initial consultation our implant dentist, Dr Ashley Sim, will use x-rays and scans to establish if pre-treatment is required and will explain this further.

Pre-treatment

Bone expansion

Your dentist may recommend a bone expansion if your jawbone is too narrow for a dental implant to be fitted. This involves making a small hole into your jawbone where your implant will eventually sit and using bone graft material to widen and strengthen the bone. The bone will be left to heal before a dental implant can be successfully installed.

Bone graft

Bone grafting is a treatment that is used to strengthen the area of bone your dental implant will be inserted into. This involves taking bone from elsewhere in the mouth and placing it in the area to be strengthened. After a number of months, this will fuse together, creating a stronger base for your implant.

Sinus lift

If there is not enough space to fit a dental implant in your upper jaw, Dr Ashley may recommend a sinus lift. This involves moving the sinus membrane upwards to create space in your bone for your new tooth. Once the membrane has been moved, a bone graft will fill the space that has been created to make a suitable space for your dental implant.

Once Dr Ashley is happy your bones and gums are healthy, your dental implant treatment can begin.

I had a broken molar which required repair/filling. Was not a patient of the dental Surgery but received excellent care - most important aspect of this whole experience was that i was seen within 3 working days.

Both practitioners were personable, reassuring and put me at ease. They both very thorough.

Dr Ahmet was considerate and professional at all times (as he has been over the many years I have known him). The filling was not really a surprise. It was done swiftly and without anasthesia. a little pain but we both ploughed through that. Surgery Nurse and Reception Staff were supportive and helpful (change in Medication from Warfarin and Apixaban was carried out smoothly). I'll be back in6 months from Hygienist.

9th August 2026

As a nervous patient, Jacob and the dental nurse made me feel totally at ease. Asking me if I’d like the procedure to be explained to me as they went along. General chatting and distraction from the radio. He was very patient and took everything slowly.

I needed a quick appointment and treatment as I had cracked a tooth and filling. I phoned and managed to get an appointment the same day with my regular dentist. Ahmed saw me and did the filling immediately. Could not have asked for better service.
