Although the end results might look similar cosmetically, restoration procedures that involve crowns and dental bonding are very different. Also, so are the conditions that will determine when one approach is needed over another.
What Helps Determine If Dental Bonding is best?
Typically for restorations, a professional will consider a more cosmetic approach, such as repairing superficial cracks or filling in gaps between teeth, however, bonding is recommended. Bonding is also used to lengthen misshapen or small teeth and to whiten teeth discolored by things like tetracycline or coffee. Bonding is usually done on teeth in the front of the mouth, such as the incisors, rather than teeth in the back, called the molars. Because the surface of incisors are more vertical, damage is mostly isolated to that part of the tooth, not compromising the bone and root underneath.
The teeth in front are usually less prone to wear and tear than molars are, which are usually subjected to chewing, so dentists can use materials that are less forgiving when rebuilding and repairing gaps and chips. After prepping the tooth or teeth by roughening and conditioning the area(s), the dentist will apply and sculpt the resin to match the shape of the tooth before hardening it with a high intensity, hand-held light which is harmless.
When a Crown Makes More Sense
Because of the advances in today’s technology, crowns can sometimes be completed in only one visit. A recent development is CEREC, or Ceramic Reconstruction, which is a high-precision, patented procedure done in addition to traditional porcelain crowns. Different from ceramic crowns, which must be sent to an outside lab, CEREC is done with a combination of in-house milling and CAD-CAM imaging. Your dentist will have several factors to help determine the best approach according to your particular needs. Whichever case, crowns are made so they will fit on top of your teeth.
Crowns are used as an alternative to fillings in the more involved cases. This is mainly applicable in cases where parts of a tooth have been removed so that the tooth’s function and appearance can be restored after a restorative procedure like a root canal. Since crowns cover the remaining part of the tooth completely, it is completely protected, and your dentist can ensure a snug a fit against the gum line. Even though crowns may also be used on the front teeth to an equal or better effect as bonding, the reverse – bonding on molars – is not as common or effective because of the demands on molars are greater than on incisors. This is mainly why crowns are preferred even in the case of molars that are more cosmetic, such as covering discolored or stained teeth.
Which Approach Is Right For You?
Although we do hope this overview of a few of the differences in crowns and bonding has been a help to you, the best way for you to know what is right for your needs, is a visit with your local dentist to talk about your dental concerns. Only then will he be able to present the options to you that make the most sense according to your budget and schedule, and the severity and location.
