Tooth Abscess: Symptoms and Emergency Care
·
A dental abscess is a pocket of pus from a bacterial infection, either inside the tooth at the root tip or in the gum beside it. It does not resolve on its own, antibiotics alone do not cure it, and in a small number of cases the infection spreads somewhere dangerous. Most abscesses are treated in a single appointment. We keep same day slots at our Midtown Houston office for exactly this.

How to Tell It Is an Abscess
The classic picture is hard to mistake once you know it.
• Severe, constant, throbbing pain, often radiating into the jaw, ear or neck on that side. It is usually worse lying down, which is why abscesses wake people at 3am.
• Pain on biting or touching the tooth. That specific tenderness comes from pressure at the root tip.
• Swelling of the gum, cheek or jaw. Sometimes a visible bump on the gum.
• A bad taste or foul smell, particularly if the abscess drains, at which point the pain often drops sharply. The infection has not gone away. It has found an exit.
• Sensitivity to hot that lingers, while cold may briefly relieve it. That combination is fairly specific to a dying or dead pulp.
• Swollen, tender lymph nodes under the jaw.
• Fever or feeling generally unwell.
• A tooth that has darkened.
One warning: pain that stops on its own is not recovery. When the nerve finally dies, the tooth goes quiet while the infection continues into the bone.
When It Is a Medical Emergency
Go to an emergency room or call 911 immediately, do not wait for a dental appointment, if you have any of the following:
• Difficulty breathing or swallowing, or a feeling that your throat is closing
• Swelling in the floor of the mouth, under the tongue, or spreading down the neck
• Swelling that has closed your eye or is spreading toward it
• High fever with chills, confusion, or a racing heart
• You cannot open your mouth more than a couple of centimeters
These are signs of an infection spreading through the deep tissue spaces of the head and neck, and it is genuinely life threatening. It is rare. It is also the reason nobody in dentistry treats a facial swelling casually.
Everything short of that list should be seen the same day or the next day. Call us at (713) 322-7474 and say the word abscess.
What Causes It
Three routes, and they need different treatment.
A periapical abscess starts inside the tooth. Decay, a deep filling or a crack lets bacteria reach the pulp. The pulp dies, and the infection exits through the root tip into the bone. This is the most common type and the one that needs root canal treatment.
A periodontal abscess forms in the gum pocket beside the tooth, in a patient who already has gum disease. The tooth may still be alive. Treatment is drainage and cleaning out the pocket rather than a root canal.
A pericoronal abscess develops under the gum flap over a partly erupted wisdom tooth. Food and bacteria get trapped under the flap. It usually recurs until the tooth comes out.
The risk factors are unsurprising: untreated decay, a cracked tooth, a failed previous root canal, uncontrolled diabetes, smoking, and a dry mouth from medication.
What Will Not Fix It
Antibiotics alone do not cure an abscess. They can reduce swelling and stop the infection spreading, which is genuinely useful and sometimes necessary before treatment, but the source is inside a tooth that no longer has a blood supply, so the drug never reaches the bacteria there. The infection comes back within weeks of finishing the course. If a clinic hands you antibiotics with no treatment plan, that is an incomplete answer.
Do not try to drain it yourself. Piercing a gum swelling with anything non sterile pushes bacteria deeper into tissue and can turn a contained infection into a spreading one.
Do not put aspirin against the gum. It causes a chemical burn of the tissue and does nothing for the tooth. Do not give aspirin to anyone under 18 because of the risk of Reye's syndrome.
And do not wait for it to settle. Every abscess we see that has become serious started as one somebody was waiting out.
Treatment and What It Costs in Houston
The first step is always draining the infection and removing its source. Which route depends on which tooth and how much of it is left, and that is also what sets the average cost of treating a tooth abscess in Houston.
• Root canal. The tooth is opened, the infected pulp is removed, the canals are disinfected and sealed. The pressure relief when the tooth is opened is immediate and dramatic. The fee depends on which tooth it is, because front teeth have fewer canals than molars, and a crown afterward protects it, which is quoted separately.
• Retreatment, when an abscess forms under a previous root canal. It runs somewhat higher than a first root canal because the old filling material has to come out first.
• Apicoectomy, when the infection sits at the root tip and cannot be reached through the canal. It is a surgical procedure and priced accordingly.
• Extraction, when the tooth cannot be restored, is the least expensive route. A bone graft to preserve the socket for a future implant is a separate line item, and a single implant with its crown is the larger long-term investment.
• Periodontal abscess: drainage and cleaning of the pocket, with scaling and root planing afterward, priced per quadrant, so the exam determines the total.
• It all starts with a new patient exam with X rays, our least expensive visit.
Antibiotics are prescribed alongside treatment when there is spreading swelling, fever, or a medical reason to cover you. Not instead of it.
We verify your insurance benefits before treatment and give you your share in writing. Cherry, Affirm and Sunbit are available for the balance, and (713) 322-7474 gets you today's exact fee for each option.
Until You Can Be Seen
This manages pain. It does not treat the infection, and it does not replace the appointment.
• Ibuprofen and acetaminophen together, at standard over the counter doses and if you can take both safely, work better for dental pain than either alone. Follow the packaging and your doctor's advice if you take other medication.
• Rinse gently with warm salt water, half a teaspoon in a cup of warm water, several times a day. If the abscess is draining, this helps keep it draining.
• A cold compress on the outside of the cheek for the swelling. Not heat, which encourages the infection to spread.
• Sleep with your head elevated on extra pillows. It genuinely reduces the throbbing.
• Soft food, chew on the other side, and avoid anything very hot or very cold.
If swelling increases, if you develop a fever, or if opening your mouth becomes difficult, stop waiting and get seen.
Same Day Care in Midtown Houston
We hold same day emergency appointments and you do not need to be an existing patient or have a referral. Call (713) 322-7474 and describe the swelling. If it is after hours, the same number reaches our on call doctor.
What happens when you arrive: an examination, an X ray to see the root tip and the extent of the infection, and a diagnosis of which type of abscess it is. In most cases treatment starts at that visit, because leaving an abscess untreated over a weekend is how a manageable problem becomes a hospital problem.
Our endodontists, Dr. Pedram Bohluli, Columbia trained in endodontics, with a Master’s and PhD in Biomedical Engineering, and Dr. Parastou Terrany, handle the teeth that can be saved. Our oral and maxillofacial surgeons, including Dr. Jonathan Rosenstein, who is board certified and a Diplomate of the American Board of Oral and Maxillofacial Surgery, handle the ones that cannot.
We are at 106 W Gray St in Midtown, minutes from Montrose, River Oaks, Downtown, the Museum District and the Texas Medical Center, with Saturday appointments.
Frequently asked
What are the symptoms of an abscessed tooth?
Severe throbbing pain that often radiates to the jaw, ear or neck and worsens lying down, pain on biting or touching the tooth, swelling of the gum, cheek or jaw, a bad taste if it drains, lingering sensitivity to hot, swollen lymph nodes under the jaw, fever, and sometimes a darkened tooth. Pain that suddenly stops is not recovery; it usually means the nerve has died while the infection continues.
Is a tooth abscess an emergency?
It becomes a medical emergency with difficulty breathing or swallowing, swelling under the tongue or spreading down the neck, swelling closing the eye, high fever with chills or confusion, or inability to open your mouth more than a couple of centimeters. Go to an emergency room immediately for any of those. Everything short of that should be seen the same day or the next day at a dental office.
Will antibiotics cure a tooth abscess?
No. Antibiotics reduce swelling and can stop an infection spreading, which is useful and sometimes necessary before treatment, but the source is inside a tooth with no blood supply so the drug never reaches the bacteria there. The infection returns within weeks of finishing the course. Antibiotics are prescribed alongside a root canal, drainage or extraction, never instead of one.
How much does it cost to treat an abscessed tooth in Houston?
It depends on which treatment the exam calls for. At Omega Dental Specialists in Midtown Houston, an extraction is the least expensive route, a root canal costs more and varies by tooth, retreatment of a previous root canal runs somewhat higher, and an apicoectomy is a surgical procedure priced accordingly. A bone graft and a single implant with its crown are separate, larger investments. We verify your insurance benefits, give you your share in writing, and quote today's exact fee at (713) 322-7474.
Can a tooth abscess go away on its own?
No. It can appear to, because an abscess that finds a drainage path through the gum releases its pressure and the pain drops sharply. The infection is still there and the bone at the root tip continues to be destroyed. A draining gum pimple that comes and goes is one of the most commonly ignored signs of an ongoing infection.
What can I do for abscess pain at home tonight?
Ibuprofen and acetaminophen together at standard over the counter doses, if you can safely take both, work better for dental pain than either alone. Rinse gently with warm salt water several times a day. Use a cold compress on the cheek, not heat. Sleep with your head elevated. Never place aspirin against the gum, which burns the tissue. None of this treats the infection.
Can an abscessed tooth be saved?
Usually yes. A root canal removes the infected pulp and seals the tooth, and the relief when the tooth is opened is immediate. Where the infection sits at the root tip and cannot be reached through the canal, an apicoectomy treats it surgically. Teeth that cannot be saved are generally those with a vertical root fracture or too little sound structure left to restore.
