Dental Inlays & Onlays

Traditionally, inlays replace a small amount of tooth structure left by a cavity, just as fillings do. They filled and sealed the tooth but were made only of gold. Inlays today are made of tooth-colored material such as ceramic, porcelain, or a specialized dental composite.

The inlay consists of the tooth-colored material and bonding, a clear fluid material, to attach the inlay to the tooth. As explained by the American College of Prosthodontists, "Using a clear fluid version of this material to seal the exposed surfaces of the teeth decreases sensitivity to temperature changes and certain types of foods." The bonding material is also tooth-colored and may help improve the color and appearance of stained or discolored teeth.

Tax savings represent the main benefit of an FSA. Since the funds are removed before taxes, employees have a lower taxable income. Some employees find that an FSA increases their take-home pay. The funds in an FSA are available at all times, with few restrictions. Most FSAs are linked to a debit card for added convenience. Patients can then use their FSA debit card at their doctor, dentist, or pharmacy. Patients usually do not need pre-approval or to do other paperwork.

However, employees can only contribute a certain amount of money each year. For most employees, the limit is $2,750 per year. Spouses can also contribute an equal amount to their own FSA. Additionally, FSA funds are tied to an employer. If an employee changes jobs, they cannot keep their current FSA

FSAs funds are "use it or lose it." At the end of the year, employees can roll over up to $500. The remaining unused funds are forfeited to the employer. Employees must keep an eye on their FSA balance. It's up to each patient to ensure that they use their funds before they expire.

Many patients confuse FSAs with health savings accounts (HSAs). These programs are similar, but they have a few key differences. With an FSA, employees can use their funds as a line of credit. With HSAs, employees can only spend money they have already saved. HSAs are also transferrable: employees can keep their HSAs if they change jobs.

Similar to the onlay and crown comparison, there are several things to keep in mind when looking at inlays versus fillings. Traditional fillings are typically recommended for minor cavities, while inlays can be used to fill larger cavities that are not severe enough to need a crown. While inlays are more durable than fillings, fillings can be placed much more quickly. 

An inlay takes at least two visits - one for the impression to be made and one for the placement.

An onlay is generally used when a patient has a small hole that is only a tad larger than an inlay or old filling. In most cases, an onlay can cover the cavity hole and surrounding area. Onlays are a less aggressive restoration treatment than crowns as a smaller amount of tooth structure needs to be removed.

On the other hand, crowns are caps or covers used to restore the function and appearance of a tooth but replace the tooth itself. According to the article on caps and crowns, "Crowns are indicated for teeth with very large fillings, teeth that have had a root canal, fractured teeth, worn teeth due to grinding, and misshapen and/or discolored teeth." The key distinguishing factor a dentist will use to determine the right choice for a patient is the size of the cavity.

Dental insurance coverage varies from person to person. You will want to reach out to your insurance provider directly to find out if they cover inlays and onlays. Our staff will help you determine any out-of-pocket costs.

An inlay is meant to fit in the center of a back tooth and covers only a portion of the chewing surface. An onlay will cover more of the tooth, such as the small points or ridges along the sides. Both inlays and onlays are made from impressions of the area so they are a perfect fit.

Since inlays and onlays are made off-site, they require two office visits to be put into place. Once the decay and damaged material are removed, our dentist will make an impression of the site to be filled. A temporary covering will protect your tooth between visits.

After the procedure, there is usually a little discomfort, but most patients can adapt to the new chewing surface quickly. Sometimes the tissues around the area worked on are sore or the tooth is sensitive to hot and cold. These issues should fix themselves in one or two days.
