How Long Does it take for a Cavity to Destroy a Tooth

A straightforward filling might only take 20 minutes. Onlays and inlays can now be created in a single appointment by many dental offices thanks to technology, but a larger filling or multiple fillings may take longer. Additionally, the process might take longer or necessitate a second visit, depending on the materials used for the filling.

  • Although it takes longer, composite resin material can be applied to your tooth in just one visit.

  • An imprint could be used to create certain composite fillings. To bind the filling, a second appointment is necessary.

  • Inlays and Onlays made of gold or porcelain may only be completed in a single appointment if your dental clinic has the necessary tools.

  • Otherwise, it needs many trips. The dentist will fill the cavity and take an imprint on your tooth during the first session. To make the filling, they’ll send the imprint to a lab. The filling will be bonded to your tooth during your next appointment.

  • In most cases, replacing an old filling takes the same amount of time as installing the new one. If the previous filling material has to be drilled out, it can take a little bit longer. A medical practitioner will remove the old filling material and clean the cavity before placing the new filling.

Dental Cavities Types

Dental cavities come in three different varieties.

1. Cavities with a Smooth Surface

Additionally called occlusal cavities, they exist. Only the enamel has been impacted. A patient could have persistent foul breath, difficulty chewing, a small hole on the tooth’s surface, and swollen gums surrounding the impacted tooth.

Occlusal cavities are rare and only occur on the molars. The molars are in the back of the mouth, where they are less likely to be brushed than the front teeth.

2. Crack Cavities

These are located in the deep grooves on the molars and are also referred to as pit cavities. People who do not routinely clean their teeth are more likely to develop these frequent cavities because food particles and plaque (the bacteria that cause tooth decay) may easily accumulate in these grooves.

These cavities will be filled by a dentist using a sealant. Sealants are thin coatings applied to the surface of the tooth to stop future deterioration. The sealant adheres to the grooves on the molars and shields the deeper layers from the cavity’s growth.

3. Root craters

These develop underneath the gum line, near the tooth’s root. People who have receding gums or poor dental hygiene are often affected by the bacteria’s acidic effects on the cementum. Since root cavities form more quickly than other types of cavities, they need more care.

In order to remove the rotted pulp, clean the region, and then seal it off from future decay, the dentist will need to conduct a root canal if the cavity involves the pulp.

Early detection of the root cavity makes treatment considerably simpler. A fluoride treatment will guarantee that the cavity doesn’t become any deeper, and a comprehensive cleaning will get rid of all the plaque.

How long does it take a youngster to get a filling?

  1. Even with excellent ■■■■ hygiene practices and a balanced diet, cavities in youngsters are very common. One in five 5-11-year-olds has an unfilled cavity, according to the CDC (CDC).

  2. With a few extra factors taken into account, fillings for youngsters generally take the same length of time as fillings for adults.

  3. Anesthesia may be required if a youngster younger than five cannot sit still for 20 minutes. Due to this, the visit may start later than expected, and your kid may need some recuperation time before you can take them home. Laughing gas, often known as nitrous oxide, may be used safely to keep kids motionless while being pumped up.

  4. If your kid requires any modifications, you should discuss them with your dentist. A competent pediatric dentist should be able to predict the precise time needed to complete your child’s filling.

Fillings that are simple take 20 minutes. Onlays and inlays are often created in a single appointment at dental offices, although substantial fillings may need more time. It can take longer or need a second visit, depending on the filling material. Early discovery of root cavities facilitates therapy. All plaque will be removed by thorough cleaning, and fluoride will stop the cavity from becoming bigger.

Dental Filling Procedure

The different materials utilized to fill your cavity will be covered by your dentist. The following materials, according to the American Dental Association (ADA), are some of the most popular choices:

Metallic silver fillings.

These are metal amalgams, which are composed of copper, tin, silver, and mercury. The ADA claims that this substance is more cost-effective than other materials and more long-lasting than tooth-colored fillings. The mercury concentration may worry some individuals, but the ADA hasn’t found any medical proof that amalgam fillings are dangerous. Nevertheless, these fillings are being phased out.

White fillings on the teeth (composites).

These are a combination of acrylic resin and glass or quartz particles. According to the ADA, this substance is strong and costs a little bit more than metal amalgams.

Amalgam fillings.

Although more costly, this alloy of gold, copper, and other metals is strong. They don’t seem natural, either. Following the dentist’s imprint of your tooth, gold fillings are often created in a laboratory.

Ionomer glass fillings.

Although they are tooth-colored fillings as well, they are not as durable as composites. They are constructed of fluoride-containing glass and acrylic, which may help prevent cavities. They cost more than amalgams and are often used on kid teeth.

ceramic fillings

These cost almost the same as gold fillings but have a more organic appearance. After the dentist makes an imprint on your tooth, they are created in a lab.

Cavities Prevention

Experiencing the Filling Afterward

It’s typical to feel some tooth sensitivity or discomfort after the filling operation. This may last for a few days. Avoiding foods that promote sensitivity, such as hot or cold beverages, sugary meals, and soft drinks, is the best course of action. If the pain or discomfort lasts more than a few days, you should make an appointment with your dentist.

Certain fillings need time to set. Thus, consuming sticky foods may cause your filling to fall out. When you can eat sticky or hard foods again, ask your dentist.

After the surgery, the anesthetic should start to wear off, so you could have pain afterward. Feel free to make another trip to the dentist if the pain persists.

What to anticipate

Fillings are often a quick process:

Your dentist will first inspect your mouth and use dental tools to look for cavities. To determine the degree of dental decay, they could take an X-ray of the affected tooth or teeth.

You’ll get a local anesthetic to make the tooth region more comfortable. This will lessen any potential discomfort. If the filling is on the surface of the tooth, you may not require anesthesia.

After numbing the area, your dentist will likely use a dental drill to remove the rot through the tooth enamel. The use of a laser or an air abrasion instrument by dentists is possible, although it is uncommon.

Your dentist will next fill the hole after sterilizing and preparing the region for the filling. A blue-wavelength laser is used to harden or cure some filler types.

Your dentist will next polish the tooth and make sure your bite is proper before completing the procedure.

You shouldn’t feel any pain when the numbing medicine wears off, although your tooth may be sensitive. For one or two days, stay away from iced or very hot meals and beverages. You may generally continue eating like you normally would.

Metals like gold, copper, and others are strong yet expensive. Not organic. A dental lab uses dental imprints to create gold fillings. Fillings need to be secured. Fillings may get loosened by sticky foods. When are foods that are hard or sticky okay to eat? Consult a dentist.
