Emax inlay and crown units
It’s been recommended I have an Emax unit!! Emax is a porcelain material that we use to replace fillings and broken teeth to make them look natural again. We recommend the use of Emax porcelain as it is the strongest, most natural looking material we can put onto a tooth to make it as close to enamel as possible. By bonding Emax onto the tooth we are giving it the strength to last for many years to come.
Crowns were previously often made using porcelain bonded to precious metal. Using a metal core meant that the margins of the crown could be seen making a black line appearance between the gum and tooth. The porcelain looked uniform in colour and were often very opaque.
Emax restorations do not have a metal core so the light can shine through them as it would with a natural tooth. It will look like you have a natural tooth and never had a filling before on that tooth.
What is the difference between a crown and an inlay?? A crown fits over the outer surface of your natural tooth, leaving none of your natural tooth visible. Crowns are normally used on teeth that are more broken down or if there has been a post put in after a root treatment when the nerve has died off.
An inlay (or onlay) avoids any natural tooth destruction, it simply replaces the current or broken filling that was in place or repairs a break in the natural tooth.
Why can I not have a filling?? We recommend Emax in all situations where a normal filling, either amalgam or tooth coloured, is not suitable.
Amalgam fillings do not bond to tooth tissue therefore more destruction is made to tooth as the filling needs to be locked into place. Although they can last for many years they are unsightly in the mouth and can cause a tooth to break down further as the amalgam can cause the remainder of the tooth to flex and break off.
Tooth coloured fillings can be suitable for small areas of tooth that have decay or have broken down, normally anything over two or more surfaces of the tooth we believe is better to be restored using Emax. Tooth coloured fillings are not as strong and cannot be guaranteed for as long as Emax and can stain or chip more readily. Emax won’t change colour as a tooth coloured filling will.
Are they expensive?? We believe they are a bargain !
We cannot make Emax restorations in the surgery, so we need to take impressions of your mouth and send them to a top lab for it to be made, which means we have a lab bill to pay. It takes two appointments to prepare your tooth and fit it. Each one is unique and this individuality is reflected in the cost.
Shade of your Emax The shade of your Emax is important as we want it to match your natural teeth. Sometimes if we are having difficulty matching it we will ask you to visit our lab so they can see you and match it perfectly to the rest of your teeth and your skin tone.
Of course if you are not happy with the colour of your other teeth then why not whiten your natural teeth before we make your Emax,
then we will match your Emax to your new whiter, sparkling teeth.
Root Canal Treatments
What causes a root canal treatment to be needed?? If the nerve inside your tooth has died off then you have probably been told you need a root canal treatment. The soft tissue in the centre of your tooth is known as the pulp. The pulp runs through the inside of your tooth and into your gum and jaw bone. If this pulp becomes infected by bacteria then it will begin to die. If left there is a risk that the infection could spread down into the root canal and develop into a painful abscess.
A nerve can die as a result of a trauma to the tooth or because a tooth has become decayed and the decay has gone through to the pulp chamber.
Root canal treatments are designed to save the tooth and prevent the spread of infection. The damaged pulp is removed from the tooth and the root canal cleaned of all the bacteria and infection. After the bacteria have been removed, the root canal is filled using an artificial substance before being sealed.
What are the signs and symptoms that a root canal treatment is needed?? If it is clear that a nerve has died off in a tooth then a root canal treatment is needed. X rays can usually help diagnose this. However you may experience symptoms such as;
- Tenderness or pain when eating or drinking hot or cold food and drinks,
- Tenderness when touching the tooth,
- Pain upon biting or chewing,
- The tooth becomes loose,
- The gum near the affected tooth begins to swell,
- Pus may ooze from the affected tooth,
- Facial swelling.
What is a root canal treatment?? Once diagnosed that the nerve has died or is dying, we will need to begin treatment. If the nerve is in the process of dying or you have an infection around the tooth we mayl give you some antibiotics to settle it down. When we start to clean the canal depends on individual circumstances.
A root canal treatment normally takes two appointments. At the first appointment we will open the top of your tooth until we can see and access the pulp chamber. Any remaining tooth pulp or nerve is removed and cleaned using small files and an antibacterial solution. A dressing is then placed inside the canal and a temporary dressing placed on top, this makes sure all the bacteria is out of the canal and that gum and surrounding area is healing well before the second part of the treatment.
At the second appointment, using the small files we will the shape and enlarge the canals, as they are often oval and very narrow, so they can be easily filled. Different teeth have different numbers of canals so each root canal treatment is different, with some taking longer than others so do not worry if yours takes a few more visits, it may just have 3 or 4 canals that take more time to clean. Root canal treatments require a lot of attention to detail.
Once the canals have been thoroughly cleaned and shaped correctly a sealant material and gutta perca points are placed into the canal and a filling placed on top to keep it secure.
Will it be painful?? Root canal treatments are commonly thought of as being a painful procedure. However unless you specifically request anesthetic we often carry out the procedure without anesthetic as it is normally a pain free procedure.
How long will my root canal treated tooth last?? If you have a good oral hygiene regime and an adequate seal there is no reason why your tooth shouldn’t last many years. Root-filled teeth can often become more brittle so sometimes placing a crown or inlay on to the tooth in the future may be an idea to protect it from breaking.
If a nerve dies off as a result of trauma to the tooth then it may become
darker over time but this can be solved with internal whitening to the tooth if you find it bothers you.
Core build up
A core build up is a restoration used to sufficiently build up tooth structure for a future restoration. It creates retention for a crown and strengthens the tooth. It is ideal if tooth structure has been lost due to tooth decay or a fracture.
A core build up may also be required if the tooth has been root treated. The post will be placed into the root canal space of the tooth, removing some of the gutta percha filling material that will be in the canal from the completed root treatment.
Once a post is cemented into place a composite core material is used to build up the tooth to make it
cosmetically and functionally a normal tooth again. In the majority of cases a porcelain unit would be placed on top as this is the strongest solution we have.
