What is a Palatal Abscess?

This is an abscess – but it’s not on the palate.

Many patients will come to a dental office stating something to the effect of “I have an abscess” or “I have this bump here so it must be an abscess.” But what is an abscess? And more specifically, what is a palatal abscess? In this post, we will not only describe it to you, but we will show you incredibly detailed photos!

An Abscess Defined

Before we talk about a specific type of dental abscess – a palatal – let’s first define what an abscess is:

A circumscribed collection of purulent exudate appearing in an acute or chronic localized infection frequently associated with swelling and other signs of inflammation.

A more simplified definition would be:

A localized collection of pus associated with an infection.

We can further define an abscess based upon the location, consistency of the pus, and other variables. For this post, we are focusing on abscesses located on the palate (the roof of your mouth).

So a Palatal Abscess is Associated with the Palate?

A palatal abscess is a collection of pus associated with an infected tooth that drains onto the palate (a.k.a. roof of the mouth).

When an infection with a tooth develops, it most often begins at the tip of the root deep inside the bone. The infection expands within the bone, with pressure building. Ultimately, the infection perforates the bone, and enters the soft tissue, which creates a swelling.

In a palatal abscess, the infection spreads from the tip of the root towards the palate, resulting in swelling on the roof of the mouth near the offending tooth.

Palatal Abscess Photo #1

The photo below was taken in my dental office in Orange, CT. She developed a LARGE swelling on the roof of her mouth on the right hand side:

In the above case, this 70 year old female split her upper right molar in half. This lead to an infection which culminated in a large palatal swelling. The solution was to remove the tooth and drain the abscess – which I did! Within a week, she was back to normal (except she no longer had the tooth).

Palatal Abscess Photo #2

This photo was taken on a mid 20s female. You are looking up at her palate. The infected tooth was #7 – her right maxilary lateral incisor. You notice a LARGE swelling.

Treatment for this patient involved draining the abscess and then performing a root canal. I am pleased to report that the treatment succeeded and that she still has the tooth!

Palatal Abscess Photo #3

This patient in her mid 70s developed swelling in the upper left. She called us but was not able to arrange transportation to see us for approximately 48 hours. In the interim, we prescribed antibiotics for her, which she began taking. When she arrived, she reported that there had been a swelling, but it had suddenty went down rapidly, accompanied by a metallic taste.

In the above photo, the tissue is only slightly swollen now, but there is now a large ulceration. Treatment involved extracting the offending tooth. She was much happier after the tooth was gone!

I hope you enjoyed this post and the photos. I have dozens more photos. Want to see more? Leave a comment and I’ll post more.

Getting an Infected Tooth Pulled

In 2016, I tackled this very subject as Dental MythBuster #16 – You Shouldn’t Have an Infected Tooth Pulled. In this post, I dispelled the myth that if there is an active abscess or other type of infection with a tooth, it should not be removed. I wrote this Dental MythBuster because I had previously encountered some individuals who believed that you are supposed to give antibiotics ONLY and not treat the infection surgically.

This “no pulling when infected” myth was in full force when I posted this video in February 2019 on our YouTube Channel of me treating a patient with a large, life threatening infection. In spite of this, there were posters who were somehow suggesting that I should not remove the tooth? Huh?

Let’s look at the video that provoked these comments:

It is a very popular video with over 1.6 million views as of 9/2019. As a result, there are many comments. But if you scroll through them, you will occasionally see commenters assert that removal should not have been done.

The “You Can’t Have an Infected Tooth Pulled” Myth in Action

Let’s look at one YouTuber who goes by the name rancar29:

Youtube comment on getting an infected tooth pulled

In the above comment, rancar29 claims that removal would cause sepsis, and that surgical intervention should not have been done at that time.  Apparently, he/she feels that a couple of orally administered pills will cure this infection and that the tooth – the root cause of the infection – should stay put.

I could put forth many arguments to refute the assertions of rancar29, too many to list. But the one point worth highlighting is that with an infection of this size and in this area, bacteria are already into flooding the bloodstream. Generally speaking, removal will not “spread” the infection anymore than it is already is spreading.

Would You Still Want the Tooth in your Mouth?

So, let’s say you go to your dentist with massive swelling and pain. The pain is so intense you feel like your vision is being affected. You can barely drive properly. You can’t think straight. You get in the chair. An x-ray is taken. There is a MASSIVE infection present (but you already knew that).

If this were you, would you be OK with a couple of antibiotics pills?

The dentist then says – we’ll just give you some pills and hope the infection clears. Would you be OK with that?

Dental Infection = Infection Just Inches From Your Brain

As I outlined in a more recent post – A Toothache Can Kill You – I talked about how dental infections are close to the brain. And that even in recent times, individuals in the United States have died from untreated tooth infections.

Infections such as the one shown in this video need surgical intervention ASAP. So if you are ever in this situation, you need to get treatment quickly.  Relying on a myth that you shouldn’t get an infected tooth pulled could make you end up in the ER, or worse.

Disclaimer: as always, this post is not considered medical or dental advice. Every case is different. If you have an infection like this, seek out the expertise of a dentist or oral surgeon.


A Toothache Can Kill You

As a dentist in private practice, I see all types of outlooks and attitudes regarding toothaches and other dental conditions. I see some patients who are deeply concerned to others who say “it’s just a tooth.” Others will state something like “it’s not hurting so why should I do something about it?”

When I see a patient with an obvious infection, I will often times say something like this: “you have an infection with about 100 billion nasty bacteria less than 2 inches from your brain. Are you sure you want to ignore this?”

Let’s look at a recent case I saw in my office.

Large Dental Abscess on the Lower Right

I saw the following patient who showed up in obvious pain:

This patient came to us with a golf ball size swelling on his lower right. The culprit? A tooth!

In the above photo, you can see the obvious swelling. After an exam, it was apparent the serious infection was originating from a tooth. I was very blunt with the patient. Either you get treatment now, or you will likely be in the ER getting ready for emergency surgery in less than 48 hours.

Want to see how it ended? Then watch our YouTube video below:

Infections like this – assuming they are not so advanced so as to require hospitalization with emergency surgery – are nearly always treated using the adage “cold steel and sunshine.” This expression is referring to extraction. The tooth is removed with “cold steel” and then the roots are exposed for the first time to “sunshine”. By removing the tooth, the source of the infection is removed, the pus drains, and in nearly all cases your immune system can fight off the infection.

How an Infected Tooth can Kill You

Many individuals are still skeptical that a tooth infection can kill you. After all, it’s just a tooth some will say. Well, if you read the stories located here, here, and here, you’ll see this is not a myth. It can happen.

So how does it happen? One of the more common causes is that the infection spreads to your brain. See the photo below:

Skull showing the proximity of the upper teeth to the brain. The roots are embedded in the bones of your skull and very close to your brain.

The above photo is that of a skull (which everyone knows). The bottom arrow points to the approximate location of the roots of an upper back tooth. In most cases, the infection (bacteria, pus, swelling) originates within the tooth but then enters the rest of the body through the tips of the roots. The top arrow points to the approximate location of the base of the brain. Now, this is a two dimensional photo of a three dimensional object (brain and skull). But you should be able to see that an infection with upper teeth roots places nasty, killer bacteria less than 2 inches from you brain!

If the nasty bacteria end up in the brain, it can fatal, and very quickly. It’s that simple. This is likely what happened in the case of Deamonte Driver.

Other Ways a Tooth Infection Can Kill You

There are other ways in which an infections associated with a tooth can be fatal:

  • Suffocation – no, I’m not joking. Infections associated with lower molars can lead to swelling of the throat, leading to collapse of your airway. You are simply unable to breath. This is most commonly seen in Ludwig’s Angina.
  • Heart Failure – I’m not joking with this either. The bacteria from a lower tooth can quite easily travel downward through the neck and set up around the heart. This can lead to issues with the heart and ultimately cause the heart to fail. An example of a case is located here.
  • And many other ways. Remember, teeth are part of your body too…

In summary, it’s important to not ignore a tooth infection, even if it does not hurt. You don’t want to be like the guy in our YouTube video!
