A Porcelain Veneer is made from special clay that is hard wearing, and easy to work with for an orthodontist and dentist. A south east dentist says that it is a fabulous tool for a dentist to work with, and a great aid for patients with a dental problem that needs covering over. Like a furniture veneer a dental veneer is used to create a top coat and cover an inferior surface below it. If you have a misaligned, chipped, cracked or discoloured tooth then a Porcelain Veneer is probably what you need, as all these problems will need a cosmetic covering after work is carried out to fix many of them. Taking digital pictures your dentist will then scan them into a computer for a technician to design the veneer prior to making them. Once they are made the dentist will be ready to fit them, first they will plane the tooth of enough enamel to allow them to fit the veneer so it blends in and looks natural. The enamel will never grow back, so when the veneer comes to the end of its life cycle it will need to be replaced with another one. They last anywhere between 5-15 years depending on how well you look after them, they usually discolour at the end and that`s when they need changing. You need to treat them just like a natural tooth, and clean them in the same way as your other teeth. Brushing, flossing and avoiding staining drinks such as red wine will help keep them pristine.

Dentures have been around since prehistoric times, and man has been obsessed with them to the extent they have come up with many weird and wonderful ways to make them, says an SE1 London dentist. The Egyptians made them from sea shells and loved the colours they came in, there have also been flint, metal, plastic and even wooden dentures. At one time we used the teeth of animals to make them. Their development has been a long time in the making, and up until recently the problem of food getting lodged under them was still a big problem. These days the new style adhesives make the plate so totally sealed and hygienic that it is impossible for any foreign objects to get behind them, which has been well received by everyone who wears them. They are made out of porcelain these days which is a hard wearing clay mix that is so workable it makes the teeth look really natural. Some people can`t get on with dentures and go for a bridge or implants, but most patients are happy with their dentures. They are made to a custom design using digital photos of the patient’s mouth, that’s why there has been a big increase in their use of late. To keep them clean and germ free they are usually just dropped into a solution of sterilising fluid over night, you don`t clean them in the usual manner with a brush. Many wearers have more than one set, and some even change them on a regular basis for socialising, they are now a fashion item to many people.
Dental Implants are a complex way of getting new teeth, albeit they are false teeth. Unlike dentures which sit on a plate and are removable, the dental implant is a permanent fixture says a South East London dentist. They were fitted successfully to a patient in a Swedish University where the technique was developed over a 10 year period. It starts off with a series of digital pictures taken by the dentist; these are used to custom make the false teeth that will be eventually be fitted permanently to the jaw bone. An incision is made under local anaesthetic and a Titanium plate is slid under the gum, this is then screwed down and the incision is stitched up. This is left for 3-6 months so the bone can grow over the plate; this stops the mouth rejecting it and makes the plate part of the jaw. The gum is cut again to expose the surface of the plate which has a hole or holes already drilled and screwed in it. The dentist will now fit abutments which are titanium poles; these are screwed in and glued. The incision is stitched back up and allowed to heal. Once the stitches have dissolves the patient is ready to receive the false teeth at last, these are slid on the abutments and cemented in place. They can be used immediately and very soon the patient will forget they even have them in. They need no special care either, you just clean your teeth as normal.
A Dental Crown is also known as a cap, it is either made from a blank square of porcelain or by mixing up a powder blend and laying it on in stages, says a London SE1 dentist. A root canal is a common use for a dental crown, after the work is done the dentist will need to seal the hole that is created during the operation. Sometimes the dentist will have a cap/crown made beforehand, and sometimes they will simply mix up a small amount, and trowel it on layer by layer. Each layer is spread on and then sterilised and hardened using an intense light source. If the crown is pre-made it will be hollow to allow the dentist to cement it on over the top of the tooth, the tooth needs to be ground down first to the same dimensions as the hollow inside. A Bridge is a form of dental crown, the two teeth on the end of the bridge are hollowed out so they can fit onto the two teeth either side of the gap being filled in. They are an alternative to dentures which some patients don’t get on with. They aren’t the same as a veneer which is just a covering for the front of a tooth; a crown is literally that, a topping to a tooth. A chipped tooth will often be ground down to get rid of the damaged area; it is then topped off with a crown. This is then polished to hide the join; a crown is cleaned the same way as your teeth.
A Dental Bridge is a false tooth, it could best be described as a permanently fixed denture, says a South East London dentist. The bridge is exactly what it says it is. When a tooth is lost it leaves a gap, and this is generally filled with a false tooth to keep eating habits and the smile in pristine condition. The bridge consists of three or more teeth, all of which are usually made from Porcelain and joined together. The teeth on the edges are also hollow as they will fit over the good teeth either side of the gap. These are called anchors and hold the bridge tooth in position like a suspension bridge. The dentist will first take digital photos and send them to the dental technician for the bridge to be made, in fitting the bridge they will need to grind down the edge teeth to the same dimensions as the inside of the anchor teeth. The bridge is fitted and cemented in, then polished to blend the join in. The teeth can be used almost immediately and within a few weeks many patients forget they even have a false tooth. The fixture is permanent, but a damaged bridge is easily replaced, they also need no special looking after, as a denture does. You simply clean and floss them as usual. They will get a polish and the usual clean up to remove tartar when you visit your dentist for the six monthly check up. The practice dental hygiene nurse will give you more advice on caring for a bridge.
CEREC is a system that comes in 3 parts, firstly there is a digital photographic camera, secondly there is a computer program and thirdly there is a milling machine. It is all very compact and sits in the dental surgery. A London SE1 dentist says that this system is all self contained and although it is very technical, it isn`t rocket science as the expression goes. It allows a dental surgeon to custom make a false tooth, bridge, crown or veneer in the surgery while the patient is still in the chair. In the past photos would be sent to an orthodontist for them to make the false piece, this could take weeks if the practice was busy, it also meant the patient taking more time off work. With the CEREC system the false piece is made while the dentist is preparing the tooth or the mouth to accept the piece once made. It can take as little as 30 minutes to complete the whole operation, and it also means the cost is brought down as well as the anguish most of us suffer being in the dentist chair. The pictures are taken first and then scanned into the computer program; this will design the piece and produce a 3D image for the patient and dentist to view. Then using a colour coding the dentist will choose the blank block, this is generally made from porcelain, a clay that is very hard wearing. The blank is then clamped into position on the milling machine and the computer sends instructions for the machine to automatically mill the blank into the required piece.
