There are many things that could cause a toothache in Houston, Texas. In fact, a toothache is usually a sign that you have a bigger dental problem. So, our A Dental Care dental team generally recommends scheduling an appointment with your dentist, Dr. Firoz Lalani, if you’ve had a toothache for more than three days.

Some of the most common causes of a toothache include:

Tooth decay:

Tooth decay is a serious dental issue that tends to cause toothaches. If you notice a hole or sharp edge in your tooth, or if you experience pain radiating in your tooth, you might have a cavity and it’s best to get it treated as soon as possible.


Infection in the tooth and gums, which is known as an abscess, can cause a toothache. This occurs after severe tooth decay, gum disease, or an oral trauma attacks your tooth. It’s important to get it treated so you can prevent further complications, like a root canal and tooth extraction.


If you’ve fractured your tooth, whether it was because of an oral trauma or because you bit down on something hard, it’s best to get it treated immediately. A fractured tooth could cause severe pain, could invite tooth decay to form, and could increase the possibility of further breaking your tooth.

Damaged dental work:

Having a loose or broken dental crown, dental filling, or dental bridge could easily cause a toothache. It’s best to avoid playing or wiggling the damaged dental restoration. If possible, use dental cement to put it back into place until your dental appointment.

Something stuck between your teeth:

One of the most common causes of a toothache is having something stuck between your teeth. When this happens, you can rinse with saltwater and brush and floss your teeth. If the object still does not come loose, you can visit your dentist to get it professionally removed.
