A small pimple like bump on your gum can be easy to ignore, especially if it does not hurt or disappears after draining. However, when a gum boil keeps coming back, it can sometimes be a sign that a problem around a tooth or within the gum has not resolved.
Some people first notice a small red, white or yellowish bump. Others notice an unpleasant taste when the area drains. The swelling may even become smaller and feel better afterwards. That improvement can be misleading because the original cause may still be present.
At Dr Raymond Platon & Associates in Wetherill Park, our dentists assess persistent and recurring gum swellings to work out whether the source is a tooth, the surrounding gum tissues or another oral condition.
If you have noticed a gum boil that keeps returning, swelling around a tooth, dental pain, drainage or an unusual taste in your mouth, call (02) 9609 2935 to discuss an appointment. Emergency dental appointments are available during opening hours, subject to availability.
What Is a Gum Boil?
A gum boil is a common term people use to describe a small raised bump that appears on the gum.
In some cases, the bump is connected to an infection deeper around a tooth. A small drainage pathway can form from the infected area through the gum. Dentists may describe this as a draining sinus tract.
A similar looking lump can also develop from the tissues surrounding a tooth.
Importantly, not every lump on the gum is caused by an infection. Irritation, ulcers, cysts and other oral conditions can sometimes look similar. For that reason, a persistent or unexplained bump should be assessed rather than diagnosed from appearance alone.
Quick Answer: What Does a Gum Boil Mean?
A gum boil often looks like a small pimple or raised spot on the gum. It may appear red, white or yellowish and can sometimes drain fluid or pus.
It is often associated with a problem involving a tooth or the surrounding gum tissues, but not every gum lump has the same cause.
A gum boil may also be painless. This can happen when pressure from an infection is able to drain through the gum. If the bump disappears and later returns, the underlying cause may still be present.
A dentist can examine the area and may use dental X rays and other tests to work out where the problem is coming from and whether treatment is needed.
What Does a Gum Boil Look or Feel Like?
A gum boil can appear as a small pimple like bump on the gum and may be associated with an underlying dental infection.
A gum boil does not look or feel exactly the same in every person.
You may notice:
• A small pimple like bump on the gum
• A raised red, white or yellowish area
• Fluid or pus draining from the bump
• A salty or unpleasant taste in your mouth
• Tenderness around the gum
• Toothache
• Pain or discomfort when biting
• Swelling around one tooth
• A bump that becomes smaller after draining and later returns
• No pain at all
The last point is important.
A gum boil does not have to hurt for there to be an underlying dental problem.
Can You Have a Gum Boil With No Pain?
Yes.
This is one reason people sometimes leave a gum boil for much longer than they otherwise would.
An infection can sometimes create a pathway through the gum that allows fluid to drain. Once the pressure reduces, the area may feel better.
The problem is that the source may still be present.
Some people notice a repeating pattern. The gum boil appears, becomes larger, drains, becomes smaller, disappears and later comes back again.
If that keeps happening, it is worth having the area checked even if it is not painful.
Pain is only one part of the picture. A dentist may also look at how long the bump has been present, whether it has drained before, whether the nearby tooth has been painful, whether there are old fillings or crowns, whether the tooth has had root canal treatment, and whether there are changes visible on an X ray.
What Causes a Gum Boil?
There is no single cause.
A pimple like swelling on the gum may be connected to a problem inside a tooth, an infection affecting the supporting tissues around a tooth, or another condition involving the gum.
Infection Inside a Tooth
Deep decay, cracks or previous dental trauma can affect the pulp inside a tooth.
If the pulp becomes infected or loses vitality, infection can develop around the root. In some cases, the body creates a small drainage pathway through the surrounding bone and gum.
That pathway can appear as a small bump on the gum.
This also explains why the visible bump is not always directly beside the area where someone expects the problem to be.

Dental Abscess
A dental abscess is an infection involving a tooth or the surrounding tissues and may involve a collection of pus.
Possible symptoms can include:
• Toothache
• Gum swelling
• Facial swelling
• Tenderness
• Pain when biting
• Tooth sensitivity
• An unpleasant taste
• Fever or feeling unwell
Not every dental abscess causes severe pain straight away.
Healthdirect Australia advises that a tooth abscess requires professional dental assessment because the underlying infection needs appropriate management.
Gum or Periodontal Infection
The source of a gum boil is not always inside the tooth.
An infection can also develop in the tissues that support a tooth, particularly when there is gum disease or a deeper periodontal pocket.
This matters because treatment for an infection inside a tooth can be very different from treatment for an infection involving the surrounding gum.
The first step is working out where the problem is coming from.
You can learn more about our periodontal and gum care in Wetherill Park.
Previous Dental Treatment
Sometimes a bump appears near a tooth that has already had a filling, crown or root canal treatment.
That does not automatically mean the previous treatment has failed.
The tooth and the surrounding tissues need to be examined so the dentist can determine whether the bump is related to that tooth, the gum around it or another cause.
Other Causes of a Gum Lump
Not every bump on the gum is an abscess.
Other causes can include irritation, ulcers, trauma, cystic changes and other oral conditions.
If a lump keeps returning, changes in appearance, increases in size or simply does not heal, it is worth having it assessed.
Is a Gum Boil the Same as a Dental Abscess?
Not exactly.
A dental abscess describes an infection involving pus in or around a tooth or gum.
A gum boil describes the visible bump that someone notices on the gum.
Sometimes the gum boil is connected to a dental abscess and acts as a drainage point.
However, looking at the bump alone is not enough to know exactly where the problem is coming from.
That distinction is important because treatment should address the source of the problem, not just the visible bump.
What If a Gum Boil Pops?
A gum boil can sometimes rupture or drain by itself.
You may notice a sudden unpleasant taste, some fluid or pus in the mouth, less pressure and a flatter looking bump afterwards.
It can feel as though the problem has gone away.
However, drainage does not necessarily remove the source of an infection.
The opening may close again while the underlying problem remains. This is one reason some gum boils keep coming back.
If a gum boil has popped on its own, keep the area clean and arrange a dental assessment, particularly if it has happened before.
Should You Pop a Gum Boil Yourself?
No.
Do not deliberately squeeze, puncture or pop a gum boil.
Trying to drain the bump yourself does not treat the source and can irritate the surrounding tissues.
Healthdirect also advises against squeezing an abscess because doing so can contribute to spreading infection.
Will a Gum Boil Go Away on Its Own?
The visible bump can become smaller or disappear, especially after it drains.
That does not necessarily mean the underlying problem has resolved.
If the gum boil is connected to an infected tooth or a periodontal infection, the cause can remain even when the bump is no longer visible.
It is particularly worth arranging an assessment when the gum boil:
• Keeps coming back
• Has been present for several weeks
• Repeatedly fills and drains
• Appears beside the same tooth
• Leaves an unpleasant taste
• Appears near a tooth that has had previous treatment
• Is associated with tenderness, swelling or tooth pain
Why Does My Gum Boil Keep Coming Back?
A recurring gum boil can mean that the source underneath the gum is still present.
A common pattern is that the bump appears, drains, becomes smaller, disappears and then returns later.
If the visible bump is simply the drainage point, repeatedly cleaning or treating the surface will not necessarily solve what is happening underneath.
That is why a recurring gum boil should be assessed rather than repeatedly ignored.
How Does a Dentist Diagnose a Gum Boil?
A dentist does not diagnose a gum boil from appearance alone.
The first step is usually a conversation about what you have noticed.
Your dentist may ask when the bump first appeared, whether it comes and goes, whether it has drained, whether you have toothache, whether the tooth is sensitive and whether it hurts when you bite.
They may also ask whether the tooth has had previous treatment and whether you have noticed swelling, fever or other symptoms.
The dentist will then examine the gum and nearby teeth.
Depending on what they find, further assessment may involve:
• Dental X rays
• Testing how the tooth responds
• Checking whether the tooth is tender
• Examining the surrounding gum
• Measuring periodontal pockets
• Looking for decay
• Checking existing fillings or crowns
• Assessing for cracks or other damage
These findings help identify whether the problem appears to be coming from inside the tooth, from the supporting gum tissues or from another source.
A dental examination can help identify whether a gum boil is linked to a tooth, the surrounding gum tissues or another oral condition.
How Is a Gum Boil Treated?
There is no single treatment that suits every gum boil.
Treatment depends on the cause.
If the Infection Comes From Inside the Tooth
Where the tooth can be retained, treatment may involve root canal treatment in Wetherill Park.
Root canal treatment is used to remove infected or inflamed tissue from inside the tooth, clean the root canal system and seal it.
In other situations, an extraction may need to be considered if the tooth cannot predictably be restored or retained.
If the Infection Comes From the Gums
When the source is periodontal, treatment may involve cleaning and treating the tissues around the tooth, drainage where appropriate and management of the underlying gum condition.
The exact approach depends on the clinical findings.
Are Antibiotics Needed for a Gum Boil?
Not always.
Antibiotics do not replace treatment of the underlying dental problem.
They may be prescribed when there is a clinical reason to use them, such as certain spreading infections or signs that the infection is affecting the person more generally.
This is why taking antibiotics without treating the source of the problem may not provide a lasting solution.
Is There a Home Treatment for a Gum Boil?
Home care may make the area more comfortable while you arrange a dental assessment, but it does not replace finding out what is causing the problem.
While waiting to be seen, you can generally:
• Keep the area clean with gentle brushing
• Avoid squeezing or piercing the bump
• Avoid repeatedly touching the area
• Choose foods that are comfortable to chew
• Use a cold compress on the outside of the face if there is swelling
• Ask a pharmacist or doctor about suitable pain relief if needed
• Follow medication directions carefully
A warm salt water rinse may provide temporary comfort for some oral symptoms. It does not remove an infection that starts inside a tooth.
It is also worth being cautious with online remedies that promise to remove a gum boil. Some products can irritate oral tissues, and temporary improvement in the bump does not prove that the underlying problem has healed.
Gum Boil or Swollen Gum: What Is the Difference?
A gum boil usually refers to a more localised pimple like bump.
A swollen gum is a broader symptom.
Gum swelling can happen for many reasons, including plaque related inflammation, food trapping, gum disease, trauma, irritation or infection.
If the swelling is concentrated around one tooth, our guide to a swollen gum around one tooth explains some of the other possible causes.
When Is a Gum Boil Urgent?
A small painless gum boil does not automatically mean you need hospital emergency treatment.
However, you should arrange dental advice if the bump persists, repeatedly returns or appears with other symptoms.
Seek prompt dental care if you notice:
• Increasing tooth or gum pain
• Facial or jaw swelling
• Fever
• Pus or ongoing drainage
• A persistent unpleasant taste
• Pain when biting
• Difficulty opening your mouth
• Swelling that is getting larger
• Feeling generally unwell
For local urgent dental concerns, you can learn more about our emergency dental care in Wetherill Park.
When Should You Seek Emergency Medical Care?
Some dental infections can become medical emergencies.
Seek urgent medical care if swelling linked to a dental problem causes difficulty breathing, difficulty speaking, swelling around the eye or swelling extending into the neck.
These symptoms need urgent medical assessment rather than waiting for a routine dental appointment.
For life threatening symptoms, call 000.

Can a Gum Boil Be Cancer?
A pimple like bump on the gum is often discussed in relation to dental or gum infection, but it is not possible to diagnose every oral lump from appearance alone.
A persistent unexplained lump, ulcer, patch or other change inside the mouth should be assessed, particularly if it does not heal or continues to change.
The important point is not to assume that every bump is simply an abscess or, at the other extreme, something more serious.
A clinical examination helps determine what the change represents and whether further investigation is needed.
A dental examination and X rays can help identify where a gum boil is coming from and guide the appropriate treatment.

Frequently Asked Questions About Gum Boils
Can a Gum Boil Be Painless?
Yes.
A gum boil can sometimes cause little or no pain, particularly when fluid is able to drain through it.
A lack of pain does not prove that an underlying infection has resolved. If the bump persists or keeps returning, it should be assessed.
Should I Pop a Gum Boil?
No.
Do not deliberately squeeze, puncture or pop a gum boil.
Draining the visible bump does not treat the underlying cause and can irritate the surrounding tissue.
What Happens If a Gum Boil Pops by Itself?
The bump may flatten and the pressure may decrease, but the original cause can still be present.
Keep the area clean and arrange a dental assessment, especially if the bump later returns.
Can Antibiotics Get Rid of a Gum Boil?
Not necessarily.
Antibiotics are not always required and they do not replace treatment of the underlying dental source.
Your dentist will determine whether antibiotics are appropriate and whether dental treatment is needed.
Why Does My Gum Boil Keep Refilling?
A gum boil that repeatedly fills, drains and returns can indicate that the source beneath the gum has not been resolved.
This may be related to a tooth or to the surrounding periodontal tissues.
A dental examination and, where appropriate, X rays can help identify the cause.
Do Not Ignore a Gum Boil Just Because It Does Not Hurt
A gum boil can be easy to dismiss when it is small, painless or disappears after draining.
However, if the bump keeps returning, drains repeatedly, appears beside the same tooth or is accompanied by swelling, dental pain, discomfort when biting or an unusual taste in your mouth, it is worth finding out what is causing it.
