How Do Dental Crowns Work?
A better metaphorical description might be to think of them as motorcycle helmets.In much the same way as a motorcycle helmet totally encapsulates your head, so too crowns are designed to totally encapsulate the portion of remaining tooth or implant structure above the gum line. They are also known as ‘Dental crown’, in that they cap the tooth in this way. The Texas City Dental in Texas City is conveniently located near t La Marque, Galveston and Hitchcock area is conveniently located near to the HEB and ROSS market complex is the family dentistry near by.
- Covering over an anaesthetic tooth,
- Capping off and implant,
- Providing a good seal over a tooth that has had root canal treatment,
- Protecting a weakened tooth from further fracture,
- Allowing the facilitation or attachment of a bridge/denture,
- Replacing a large filling when there is insufficient tooth to rebuild the filling.
The Process For Getting A Crown Made
During the crown preparation appointment, your dentist will get you comfortable and the tooth numb. They will then take a series of impressions of the tooth and perform a ‘tooth preparation’ This involves removing between 1 - 2 millimetres from all surface of the teeth. This reduction in tooth size will create space for the crown to fit over the tooth. After the dentist has done this they will take a very accurate impression/digital scan of the remaining tooth structure. this will be sent to a lab and the crown will be made from the impression. A shade will be chosen for the tooth.
The dentist will provide you with a temporary crown which will be in place in the interim between crown preparation and cementation of the crown. The length of time then to fit the crown will depend on if it is being totally made by hand or ‘milled’ by a 3D printing type machine.At a subsequent appointment, the temporary crown is removed and is replaced with the permanent one. Make sure your dentist shows you what it looks like before they cement it, so that you are happy with the shade match. Insist that they do this by the window or some other natural light source, so you can be sure the shade match will be right.
Crowns Made From Ceramic
These are commonly used to restore your front teeth. they are very good at blending in with the surrounding natural tooth colors, and are therefore the best option for this ‘shop front window’ of your smile!
Porcelain Fused to Metal
These crowns have a metal substructure which provides strength and a high bonding capacity in the underlying tooth. They are overlaid with porcelain which provides good aesthetics. Although they are very strong, sometimes the metal can vaguely show through giving a greyish hue to the overall crown.
Gold Alloys
These crowns are a blend of gold copper and other metals. Gold is an excellent material to use in the mouth because it is quite biocompatible (which means it doesn't tend to cause reactions with the body), and is also very malleable. This malleability means that it bonds well to the tooth, is kind to the underlying tooth, and is not liable to fracture. The main problem is of course the aesthetics. Unless you are a gangster, they tend to be confined to use at the back of the mouth!
Base Metal Alloys
These crowns are composed of non-noble metals, and they offer that advantage of being corrosion resistant and also allowing for a ‘conservative preparation’ of your recipient tooth. That means that the dentist only has to remove minimal tooth substance to create room for them.
