Size and depth of the cavity

It is quite progressive when it comes to the decay of teeth, and it commences as white spots caused by smaller amounts of mineral losses in the enamel of the tooth.

You can also aid in stopping the decay of the tooth with the right kind of dental hygiene and fluoride treatments.

You should also have a cavity that needs filling if the tooth’s enamel continues to weaken.

So, how bad do cavity fillings hurt?

There would also be the smaller cavities caught early at the earliest and the quickest amount to fix.

The discomfort can be quite minimal if your cavity is not deep enough.

Always keeps in mind that the topical numbing gel will not numb the tooth tissues and just the gums on their own, allowing the needle to not cause any kind of pain or discomfort during the injection.

A few people have a phobia of needles and often dread getting the injection more than any other part of the treatment.

Even others do not prefer the numbing sensation lingering in the tongue and cheek after the cavity is filled.

For example, the topically applied numbing gel is enough to eliminate the gums’ discomfort.

Otherwise, your dentist will stop drilling, offering you the injected anesthetic if you start feeling pain.

There are deeper cavities that need the removal of more decay, taking longer to fill up.

The deep cavities are also located closer to the tooth’s nerve endings.

This kind of cavity has the effective potential of causing a significant amount of pain during treatment.

The dentists will likely be recommending an injected anesthetic for the deeper cavities unless you are tolerant to major pain.

 

Location of the cavity 

The following are the three kinds of cavities that point out the causes of cavity:

  • smoother surface cavities are forming on the sides of the mouth
  • fissures and pits on the cavities occurring on the biting surfaces of the molars
  • root cavities are forming near the root of the tooth

Smaller root cavities are often easily filled with the anesthetic, whereas most root cavities are easy to treat when detected early.

The tooth’s root mainly contains a softer substance known as cementum allowing the decay to happen quickly.

There are exposed roots from the receding gums leading to decay quickly since the roots are not strong as the tooth’s enamel.

These are the kind of cavities that occurs if you have any kind of gum disease.

These diseases will lead to receding gum exposing the softer root surfaces on the tooth.

 

Number of cavities

Your dentist will recommend filling them once and for all if you have several cavities located in similar areas of your mouth.

It would cause additional discomfort due to the lengthy times included in the treatment of the cavity.

You will have to hold your mouth open for an extended period leading to jaw pain and gags during this treatment.

You would also need additional anesthesia for the lengthy procedures.
