Porcelain crowns and veneers – Employing science and artistry.
Porcelain or Composite Resin?
Porcelain (or ceramic) veneers are fabricated facings bonded to the front surfaces of the teeth. They are highly durable and resistant to staining and chipping. Porcelain veneers are excellent for moderate to major changes in tooth shape and texture and can be made to resemble the look of a natural tooth very closely. This type of veneer is usually manufactured by a technician in a dental laboratory and fitted by your dentist.
Composite resin (or “plastic”) veneers can be applied to the front teeth to make small to moderate changes in shape. They are useful to reshape teeth after orthodontic work, to repair small fractures or to close gaps between teeth. The material used is tooth coloured and moderately durable. These veneers can be made and fitted during one visit to your dentist, being manufactured in-house without the involvement of a laboratory.
How long do Veneers last?
Veneers are a very durable option to improve the aesthetics and functionality of your teeth. The average lifespan of dental veneers ranges from 10 years up to 25 years, though it can be less if decay is allowed to develop. Ceramic veneers are not easily broken but they can chip or fracture if subjected to trauma or other structural overload, just as unrestored teeth can. And just like natural tooth enamel, a veneer can still wear or become damaged if subjected to the destructive forces of a grinding or clenching habit.
Veneers should maintain their appearance indefinitely, although it might be desirable to replace them when, over time, gums have receded and the margins of the veneers have become visible at the gum edge, possibly with accumulated staining.
It’s rare for a veneer to become detached, but it can happen if the veneer fails to bond to the tooth due to insufficient dental enamel, suggesting that a crown may have been a more suitable choice in the first place; or, less commonly, due to an error in materials handling or performance
Veneers: Frequently Asked Questions
Your choice may be determined by your preferred treatment process, your short-term budget and your desired outcome.
The treatment process for composite resin veneers is one of direct bonding to your teeth, also known as dental bonding. (This is the same method that’s used to place a composite filling.) One of the advantages of composite veneers is that they require only one visit to the dentist. Another benefit is that composite is a cheaper option than porcelain in the shorter term.
However, a disadvantage of composite veneers is they are not as strong as the alternative – being slightly porous, they must be maintained more regularly than porcelain and are rarely permanent. They can also lose their lustre after a while, so they need to be polished; and they can discolour, needing to be replaced. These ongoing treatments add to the cost factor in the longer term.
The advantages of porcelain veneers is that they are more natural looking, are more durable and need less maintenance than composite as they don’t change colour or lose their shine. This makes them cost effective in the long term.
On the other hand, porcelain veneers, as mentioned, are manufactured either chair-side or in a laboratory after your initial consultation, and are then placed by your dentist on a second visit.
Composite veneers require just one visit. First your dentist assesses your tooth to check that there is enough natural tooth to accept the restoration. The underlying tooth is prepared, if necessary, so the veneer will adhere, though composite veneers require very little of your tooth to be sacrificed in the treatment process. Next white filling material is applied in layers and then hardened with a ‘Bluephase’ LED light. This process is then repeated until the desired length, width and shade are achieved.
For porcelain veneers your dentist assesses your tooth to check that there is enough natural tooth to accept the restoration. Next, your tooth is prepared by shaving back a thin layer to provide a surface for the porcelain to adhere to. Then, a temporary veneer is prepared and placed over the tooth while your porcelain veneer is created. About two weeks later your new porcelain veneer will replace the temporary one, and after being tried to check that it is a perfect fit, it will be permanently attached.
Your dental practitioner will advise you of any special care requirements for your new restorations, as well as any follow-up appointments that may be necessary to check your progress.
Keeping up a good dental hygiene routine, including brushing and flossing, combined with a scale and clean with your dental hygienist is very important. While the porcelain (or composite) that makes up your veneers cannot decay, the underlying teeth still can, and the teeth are vulnerable wherever they are exposed (at the back and sometimes the sides) and also where they connect with the veneers themselves. One of the benefits of dental veneers is they can protect the underlying teeth against decay. Providing you brush your teeth with fluoride toothpaste twice a day and use fluoride mouthwash regularly, dental veneers have been shown to resist decay.
It’s important to understand that the cost of any dental treatment can vary between patients, depending on the complexity of the procedure, and who performs the treatment. No two mouths are the same, and so dentists will not necessarily be able to give you an exact cost until they have thoroughly examined your teeth.
Although veneers might be considered expensive, with porcelain veneers costing more than composite veneers, patients are usually very satisfied with the results and admit that the benefits, such as improved aesthetics and (in the case of porcelain) a stronger material far outweigh the cost. There are a few different costs involved with veneers, from the X-rays to the process of bonding the veneers and the cost of the material itself.
What Are Crowns?
A dental crown, sometimes referred to as a cap, is permanently bonded to a particular tooth to improve aesthetics and function. A crown can be fitted over the remaining part of almost any prepared tooth and, if properly maintained, can last 15 years or more. When there is insufficient dental enamel to allow restoration with a dental veneer, a crown may be successfully used instead. The shape, size, colour and surface characteristics of a crown are precisely matched to surrounding teeth and provide a seamless and lasting restoration.
Crowns can be used in restorations involving:
- Heavily repaired or broken teeth
- Discoloured fillings
- A tooth needing protection following root canal therapy
Types of Crowns
There are three types of dental crown: porcelain, metal, and porcelain-fused-to-metal (PFM) crowns.
Porcelain (or all-ceramic) crowns for back teeth are made of high-strength reinforced ceramic materials (e.g. lithium disilicate or zirconia). For front teeth, porcelain crowns may be made using an aesthetically pleasing ceramic material, or they may involve two layers: a high-strength material covered with an aesthetically pleasing material. All-ceramic crowns for front teeth give a very natural, pleasing appearance; they achieve the closest match to natural, healthy teeth.
Metal crowns, which are often made of gold alloy, have been around since the early 1900s and require very minimal tooth preparation, as the metal is strong even in thin sections. When designed and constructed well, metal crowns are very durable and resistant to fracture.
PFM crowns were introduced in the 1970s and appear much more tooth-like than metal crowns due the overlying porcelain. The metal core provides strength and durability. It is common to have a thin metal margin visible around the neck of the crown on the tongue side of the crown as this preserves more tooth structure.
Crowns: Frequently Asked Questions
Dental crowns can still be subject to fracture and cavities, so it is important to look after them just as you would your natural teeth. If properly maintained through good oral hygiene and regular dental check-ups, crowns can last for many years. The material of your dental crown can affect the durability of your crown, but factors other than durability also need to be considered (such as aesthetics, survival rate and kindness to opposing teeth), so you are encouraged to discuss the different options with your dentist to choose the most suitable crown material.
All types of crown can be fabricated at an external dental laboratory, where special techniques are used to design and construct a crown that will perfectly fit your tooth. At your first appointment with your dentist, your tooth will be prepared to the desired shape and moulds will be taken. A temporary cap will be placed over the prepared tooth to protect it. Then, at a second appointment a few weeks later, the crown will be fitted and bonded in place using bonding cement.
Ceramic crowns can also be designed and milled onsite in the dental surgery, during your appointment, using CEREC CADCAM technology. CEREC allows for your tooth to be prepared and fitted with a crown all in one appointment – this means no temporary crowns, no moulds of your teeth and a much quicker procedure.
Crowns perform just like your natural teeth. While they are very durable, you still need to maintain good dental hygiene and to brush and floss the crown just as you do with your other teeth. With regular dental check-ups, proper cleaning and the use of remineralisation toothpastes, you will be able to minimise the risk of decay around your dental crown.
The costs involved with dental crowns can vary depending on the tooth that requires the crown, the materials used, and the clinician who performs treatment.
