If you have ever experienced any type of toothache, then you know how uncomfortable and painful it can be. Now there are a number of reasons a person can get affected by tooth pain. That includes those common ailments like tooth sensitivity, cracked teeth, and cavities. But there is a lesser-known cause of tooth pain – a sinus infection! You read right. Here’s some information you need to be aware of:

What is Sinusitis?

More commonly called a sinus infection, sinusitis happens when the nasal passage cavities get inflamed and swollen. Because the sinuses cannot drain, it results in a mucus build-up. This is often caused by the common cold, although allergies may also be a culprit. When the sinuses are blocked, it leads to excessive mucus creating a moist environment which is considered a fertile ground for all kinds of infections. Another symptom that can possibly affect one’s oral health is bad breath that is caused by postnasal drip.

Sinusitis and Your Tooth Pain

In most instances, the reason behind your tooth pain is quite obvious. But like we said, a sinus infection as a culprit should not be discounted, and often you can tell whether it’s the cause or not based on the location of the toothache. The roots of your upper molars are really close to the sinus cavities, and when the sinuses get infected and all swollen, it is easy to mistake the pain as originating in the teeth. If you believe you have a sinus infection, it’s best to see your doctor about it. While some over-the-counter medications can offer you pain relief, a physician is the best person to ask about the course of treatment that you need.

Easing Your Tooth Pain

Aside from seeing your doctor who may prescribe you some medicine for pain relief and treatment, you can also try a few home remedies. You can apply a warm compress on your face a few times each day. You can also increase your fluid intake to thin the mucus. You can also inhale steam several times a day and use a humidifier when you’re sleeping. When your sinus infection gets treated, you’ll find that your tooth pain will also be gone.

However, you should remember that sinus infection is just one cause of tooth pain and you should always do your best that you avoid all the other types of toothaches as well. To make sure that your teeth and gums are healthy, regularly visit Pickering Square Dental, and we’ll help you take care of your smile!

Frequently Asked Questions

What counts as a dental emergency?

Severe tooth pain, a knocked-out tooth, a cracked or broken tooth, uncontrolled bleeding, dental abscess, and lost fillings or crowns all qualify as dental emergencies. Call Pickering Square Dental at (905) 420-1777 for same-day emergency care.

Can I go to the emergency room for a dental emergency?

While the ER can manage pain and infection, they typically cannot perform dental procedures. A dental office like Pickering Square Dental is better equipped to treat the underlying cause. We reserve same-day appointments for emergencies.

What should I do if a tooth is knocked out?

Pick up the tooth by the crown, gently rinse it, and try to place it back in the socket. If that is not possible, keep it in milk or saliva. Get to our Pickering office within 30 minutes for the best chance of saving the tooth.

Dealing With an Abscessed Tooth

 An abscess is an area of puss that forms as part of the body’s effort to fight a bacterial infection. It can form in almost any part of the body. In the mouth, abscesses form in the gums, teeth, or roots of the teeth. People with a lowered resistance to infection are most likely to develop an abscess.

Bacteria can enter and cause an abscess through:

1.     Trauma (food or any debris embedded deep in the gums)

2.     Decay (a cavity) leading into the tooth nerve and blood vessels (dental pulp)
Learn more about root canal therapy.

3.     Deep gap (pocket) between the teeth and gums

An abscessed tooth usually delivers a throbbing pain that just won’t go away. The tooth will be sensitive to pressure from chewing, as well as heat. A swollen face or jaw often signals a growing infection, and jaw pain from the swelling might be present, as well. Most people develop a fever, and lymph nodes found under the jaw or in the neck area may swell and become tender. If the abscess accidentally breaks open, a sudden rush of foul-tasting and foul-smelling fluid will spill into your mouth.

Saving an abscessed tooth begins with draining the infection. The dentist will need to open up the tooth to drain the infection (puss) and there will be a need to fill the canal. This procedure is called root canal treatment. If there is no swelling present, the infection can be drained directly from the inside of the tooth.

The treatment for an abscessed tooth should be done as soon as possible. If the tooth cannot be saved, it should be extracted (removed). In doing this, the source of the infection is completely removed and the jawbone and gums are allowed to heal.

In children’s primary teeth, the treatment depends on the extent of infection. If the abscessed primary tooth is still in the early stages of infection and is not moving in the tooth socket, the infection is usually cleared out within the pulp chamber. The space would be filled with a paste such as zinc oxide eugenol. However, if the infection is advanced and has caused the tooth to move, the best thing to do is to extract the tooth.

During pregnancy, a dental abscess requires immediate attention to minimize further spread of the infection at the soonest possible time. Any risk of infection during pregnancy is a concern as the infection can be more severe in pregnant women and could be detrimental to the fetus.

If the abscess is found in the gums, the dentist might suggest that you rinse with warm salt water few times a day for several days. You might also be prescribed antibiotics to help kill the infection lessen the swelling.

Following a root canal treatment, the dentist usually requires a dental X-ray six months later to see whether healthy bone and tissue are filling the area of the abscess. If the bone does not fill in after the said treatment, a visit to the specialist is the next best step.
