Replacing mercury fillings at Alton dentist

February 6th, 2012

It may surprise you to hear that mercury fillings are still being placed in dental practices.  Mercury is a toxic metal if exposed to significant levels it can cause you harm.  Studies have shown that mercury fillings do leak mercury into your sysytem, however the levels are not high enough to cause any harm.

At Tme Dental we like to give our pateints the options available and give you our recommendations.  At the end of the day it’s your mouth and we want to give you the best advice and help you make the choices that are right for you.

When cavities are small to medium sized the current white composite fillings are a fantastic way to restore your mouth to health.  White composite fillings do not contain mercury, they bond to the teeth which helps to bring the strength of the tooth back, and they alos look like your natural tooth.

Mercury fillings over time actually weaken your teeth.  As they are metal they expand and contract and can cause micro enamel cracks to occur within the tooth.  There will be a point where either the tooth may break, the filling may break, or decay will start aorund the filling due to the enamel crack.

Catching these issues early is the best way to deal with potential problems.  Replacing mercury amalgam fillings is very common now and in the right hands is completely safe to do.

Tooth coloured fillings at Aldershot dentists

January 27th, 2012

It’s becoming very common now to replace old mercury fillings for tooth coloured options.  Advances in dental technology have resulted in tooth coloured options being the better choice in terms of strength and aesthetics.

A client came to see us at Time Dental to see what his options were for replacing his old mercury amalgam fillings.  Amalgam fillings expand and contract over time and result in internal cracks occurring in the teeth.  This is a weak point and it is only a matter of time before the tooth will break or the filling will break.

When mercury fillings are small they are straight forward to replace by a skilled dentist safely and effectively.  Using white composite fillings are the best choice for small to medium sized fillings.  Nowadays small composite fillings can last just as long as amalgam fillings.

When amalgam fillings are large it is better to replace them with either an inlay or onlay.  These are lab made restorations and are much stronger than direct composite fillings.  They can also last over 15 years and give extra support and strength to a tooth that has already been weakened by mercury amalgam fillings.  They are tooth coloured and can be made of a high grade composite or ceramic.  The ceramic inlays are the strongest and will give you great longevity.

Porcelain crowns at a dentist in Farnham

November 9th, 2011

A client came to see us requesting to change old mercury fillings that she had since a child.  Mercury fillings a currently far less acceptable for dental fillings nowadays.  Firstly they contain mercury which is a toxic metal;  secondly the tooth has to be prepared more to keep the mercury filling in place; thirdly they look awful; fourthly they actually weaken your teeth over time as they expand and contract which results in hairline cracks appearing.  The tooth or the fillng will eventaully beak possibly leaving you in a dire situation for that tooth.

Fortunately there is a solution.  When a filling is very large, it leaves the tooth weak in sturucture.  Combine this with a mercury filling and your tooth is ready to break on you.  When replacing large fillings it is common to advise crowning the tooth to protect it.  A crown is best seen as a “bomb shelter”.  It protects the tooth from all sides and prevents the cusps from breaking as they are encased with in the crown. 

There are 2 main types of crowns.  Metal crowns and tooth coloured crowns.  The metal crowns are generally made of gold.  Gold is the best metal to have in your mouth as it is time proven and also creates an affective seal.  Most people prefer the tooth coloured types as it looks more natural.  There are two main tooth coloured types.  Metal-ceramic crowns and porcelain crowns.  Metal ceramic crowns are the traditional types however due to the metal underneath it can make the gum line look bluish.  The porcelain crowns are the strongest and most natural looking crowns.  There are a number of types of porcelain crowns, they can be made of zirconia, or a pressed ceramic.  The best thing to do is discuss your options with your dentist who will able to advise you appropriately.
