Defective Enamel
There are times when dental care is disregarded by fifty one percent of the population due to the fear of pain.
Among the people who do go to the dentist, eighty percent of them say that they understand why it is needed but do not enjoy it one bit.
That may all change when aesthetic or cosmetic dentistry, which doesn't require any drilling, becomes commonplace. Dentists already have increased their popularity, it had nowhere to go but up, by giving people a new smile on life.
Composite plastic resins, which look and feel like tooth enamel, can be painted and sculpted to fill in unsightly gaps and cover up cracks, breaks and discolorations.
Most of the time, it is applied on the front teeth and considering how the resin directly adheres to the tooth, the process is called bonding.
Here, there is no need for a retention trench which involves drilling. Bonding is relatively painless occasionally an anesthetic is used if work is performed close to the gums, less expensive than a crown and can be completed during one visit.
When it comes to newly developed composites, they bond better and have a wider range of shades and this allows the new restorative materials to easily be matched with existing teeth.
Created temporarily during the bonding process are micropores which are tiny crevices in the enamel structure and this is through the use of a mild etching solution applied to the teeth.
After an intense light hardens the resin, it can bond onto teeth enamel within seconds. Following the application of the last coat is the resin being shaped and polished.
Cosmetic dentistry is becoming a true art form, where a gap is filled without making it appear the tooth has been enlarged.
Here, the tooth is wider but in order to make it appear as if there has been no changes except a gap being filled the angles of the teeth are altered to affect the way the light shines into an observer's eye.
Considering how the technique might fail, the bonding can be removed and replaced without causing trauma to the teeth. It could remineralize within 24 hours if left alone for only a small amount of enamel is removed by the etching solution.
People with defective enamel will surely have problems and if the bonding will fail it will happen during the first few days.
There are times when other kinds of restorative work cannot be replaced considering how bonding is not a panacea. A crown is advised when the structural integrity of the tooth has been compromised.
Even though more and more patients are greatly benefiting from cosmetic dentistry, some dentists are concerned too great an emphasis given on bonding will cause some people to neglect their back teeth in order to spend more money on improving the appearance of their front teeth.
When it comes to bonding, it is cheaper than crowning. Unlike the other, bonding is not a permanent solution.
After the resin is applied, discoloration and flaking occurs anywhere from three to five years and during this time the process needs to be repeated.
Apart from the avid coffee drinkers, smokers are also prone to staining. With a few improvements, it is possible for bonding on the back teeth which is at its stage of infancy to replace silver fillings and as a result reduce the need for much drilling.
The job of a dentist then is to scrape off the decayed area using a hand tool and then apply the resin directly to a substance beneath the enamel that makes up the body of the tooth called the dentin.
Serving as a sealant to correct pits and grooves in the enamel on the back teeth is the bonding process but any defects can lead to tooth decay being invited in.
There are more adults retaining their own teeth and according to the Academy of General Dentistry thirty seven percent of children today have never had a cavity. Although it seems practical, it can lead to a lot of expenses in the future.
