GPs regularly see patients with dental problems, yet more than half of survey respondents lack confidence in treating them. Here’s a practical guide.

While most dental problems are best managed by a dentist, many patients face barriers to accessing dental care, such as cost, location, or lack of availability.

A recent Healthed survey of more than 1500 GPs suggested that over 80% of respondents had seen at least one patient with dental or oral health problems in the past fortnight—and almost two thirds had seen more than one, with 22% reporting seeing five or more.

These findings are reflected in a recent study which found that approximately 1.3 % of all GP consultations in Australia involve oral health concerns.

Additionally, up to 41% of Australians report delaying or avoiding dental care due to cost, according to the Australian Bureau of Statistics.

Analysis of patient encounters between 2006 and 2016, by BEACH (Bettering the Evaluation and Care of Health), estimated that GPs in Australia manage over 1.5 million oral conditions every year.

Healthed’s survey also revealed that most GPs rely on self-education for their dental health skills. The lack of formal training in dental health helps explain why 40% of GPs feel only slightly confident to manage common dental problems and 11% feel not at all confident. Another 44% said they were moderately confident and just 5% said they were very confident.

Peter Parashos, Professor of Endodontics at the Melbourne University Dental School, says that while referral to a dentist is the ideal for most presentations, doctors need to have the skills to diagnose and offer appropriate first line treatment while the patient waits to see the dentist.

In Healthed’s survey, 60% of GPs said they frequently see patients with pain or sensitivity.

Professor Parashos believes that GPs can provide interim care by offering appropriate pain management and, if indicated, antibiotics.

Common Causes of Dental Pain

Dental pain is typically due to three main pathologies:

  • Dental caries is caused by bacteria in dental plaque that release acid, leading to the destruction of tooth tissue and subsequent inflammation (pulpitis) and, if not managed, pulp death (pulp infection and necrosis).
  • Periodontal disease is caused by specific bacteria and can result in inflammation of the supporting tissues of the teeth, ultimately leading to the destruction of the periodontal ligament and alveolar bone.
  • Pericoronitis is an infection of the soft tissue around an erupting or partially erupted tooth (usually a wisdom tooth), which becomes inflamed mainly due to plaque accumulation but exacerbated by trauma and can progress into a spreading infection if not promptly treated.


Clinicians should keep in mind that dental pain can also result from non-dental conditions, such as temporomandibular joint syndrome, maxillary sinusitis, ear infections, or cardiac conditions, and GPs should consider these possibilities when assessing a patient’s symptoms.

Assessing oral/dental pain

Making a diagnosis or at least a provisional diagnosis will help GPs decide on the best course of action, Professor Parashos says.  He recommends that as a minimum, a GP should have access to a dental examination kit with a mouth mirror, dental probe, and a periodontal probe.

Assessing oral and dental pain can be challenging, as patients may have difficulty describing their symptoms and may not have the dental knowledge to accurately identify the affected area.

Professor Parashos suggests that the SOCRATES method may be a useful tool to help GPs elicit a detailed and structured history of the patient’s pain.

  • Site: Identify the exact location of the pain, using anatomical landmarks such as teeth, gums, jaw, or tongue.
  • Onset: Determine when the pain first started, and whether it has been gradual or sudden.
  • Character: Ask the patient to describe the nature of the pain, such as throbbing, sharp, dull, or burning.
  • Radiation: Ask if the pain spreads to other areas of the mouth or face.
  • Associations: Ask if the pain is associated with any other symptoms, such as fever, swelling, bleeding, or difficulty eating or speaking.
  • Timing: Determine if the pain is constant or intermittent, and if it is worse at certain times of the day or night.
  • Exacerbating/Relieving factors: Ask if anything makes the pain worse or better, such as eating, drinking, or taking painkillers.
  • Severity: Ask the patient to rate the severity of the pain on a scale of 0 to 10, with 10 being the worst possible pain.

Management of different types of pain

The management pathway in general practice is generally guided by the type of pain the patient presents with.

Dental sensitivity and reversible pulpitis

Patients may experience a sharp pain or discomfort in response to thermal, osmotic, or tactile stimuli. This type of pain is commonly associated with dentine hypersensitivity, which can be caused by enamel erosion, gingival recession, or other factors. If the patient is experiencing this type of pain or sensitivity, the affected tooth usually has inflammation of the dental pulp, which is the loose innervated connective tissue inside the tooth. Inflamed pulp is also called reversible pulpitis. The pain subsides when the stimulus is removed.

How to treat

Refer to a dentist and recommend desensitizing toothpaste, and analgesics if required.  According to Professor Parashos, the combination of ibuprofen with paracetamol is ideal as the first line of treatment. Opioids such as codeine are not recommended.

Irreversible pulpitis

Irreversible pulpitis is a more severe form of pulp inflammation that can cause a dull, throbbing pain, which is often exacerbated by biting or tapping on the affected tooth. This condition usually arises from untreated or poorly treated reversible pulpitis. It is usually caused by deep dental caries or trauma. In some cases, irreversible pulpitis can progress to a dental abscess, which may cause more severe pain and swelling.

How to treat

Urgent referral to a dentist is required as the treatment for irreversible pulpitis usually involves root canal therapy or tooth extraction, depending on the extent of the damage to the tooth.
Effective pain relief can usually be achieved with paracetamol/ibuprofen combination. For severe pain, the Therapeutic Guidelines recommend paracetamol/ibuprofen together with an opioid, but Professor Parashos believes an opioid should only be added if the paracetamol and ibuprofen combination is ineffective.

How to treat dental pain with swelling

  • Dental pain with swelling requires urgent referral to a dentist as it may indicate an abscess or infection.
  • Systemic antibiotics are only indicated as an adjunctive treatment when there is systemic involvement or spread of infection, or if adequate drainage cannot be provided.
  • Significant swelling, especially the floor of the mouth is a serious medical emergency as it could block the airway.


How to identify and treat maxillary sinusitis

This type of pain may be caused by inflammation of the sinuses, which is sometimes due to a dental infection of a posterior maxillary tooth. It involves a continuous dull pain over the cheek and upper teeth that flares up when the patient bends forward or lies down, bites, touches it or exercises. Patients with maxillary sinusitus may have had recent upper respiratory tract infection, a history of chronic rhinitis or pain when flying.

An odontogenic cause may be suspected when:

  • the sinusitis “does not respond to medical therapy and presents with unilateral symptoms and a history of dental or jaw pain”
  • “The patient may have a history of dental caries, periodontal disease or complications with surgery in the posterior maxilla”

If you suspect the sinusitis may have a dental origin, refer the patient to a dentist. Treatment options may include antibiotics, decongestants, and referral to an endodontist if necessary.

When are antibiotics appropriate?

“Swelling where there’s obviously systemic spread of infection justifies antibiotics, but it also justifies urgent referral. If they present to a dental hospital with swelling for example, most patients will receive some sort of surgical care, such as extraction of the tooth or incision and drainage, but it’s not very often that they will prescribe antibiotics. However, as per the Therapeutic Guidelines, if dental treatment is unlikely within 24 hours, then antibiotic therapy can be started, but stressing that dental treatment MUST be sought.” – Professor Parashos

Healthed’s recent survey suggests that GPs are commonly prescribing antibiotics for dental infections, but other interventions are preferred in many cases.

Practice points on antibiotics

  • Antibiotics should only be used when there is spread to adjacent tissues causing clinical signs such as facial swelling, or in patients who are immunocompromised or have a rapidly spreading infection and/or features suggesting systemic spread.
  • Refer to emergency department if the patient has a spreading dental infection, systemic sepsis, or a risk of airway compromise.
  • Antibiotic options include phenoxymethylpenicillin, amoxicillin, amoxicillin with metronidazole, amoxicillin with clavulanate. For patients with an allergy to penicillin, clindamycin is the recommended antibiotic.
  • Prophylactic antibiotics are only recommended for high-risk dental procedures where there is a risk of infective endocarditis; for patients with prosthetic cardiac valves, a history of endocarditis, certain congenital health disease or rheumatic heart disease.
  • Careful consideration is needed when prescribing antibiotics for dental pain to avoid patient harm and antimicrobial resistance. Treating with antibiotics alone can lead to more severe episodes of acute odontogenic infection, with a risk of airway compromise.


In general, Professor Parashos says GPs should only consider prescribing antibiotics if there are signs of systemic spread of infection. If there is localised facial or intraoral swelling, the patient should be referred to their dentist or to a dental hospital for immediate management. However, as recommended above, if dental treatment is unlikely within 24 hours, then antibiotic therapy can be started, but stressing that dental treatment MUST be sought.

Communicating urgency is crucial

Unfortunately, many dentists and dental hospitals have lengthy wait times. It is important for medical practitioners to know what resources and services are available in their area to refer to.

If there’s a dental hospital or local community health centre nearby, Professor Parashos recommends liaising with them by phone to find out how likely it is they’ll be able to see patients that day, or what the waiting list is for urgent care.

When you ring up services to refer people, it’s important to communicate the degree of urgency, especially where there is facial or intraoral swelling, so they can be triaged appropriately.

Anything that is perceived not to be urgent may be delayed to the next day, so it’s important to make staff aware of bleeding, trauma, intraoral swelling or swelling due to spreading infections, or if the patient is generally very unwell so that they will be seen sooner, Professor Parashos says. Most services will have provisions for emergency services, he says.

However, where dental treatment is highly unlikely to be provided within 24 hours, a GP can commence antibiotic therapy and ensure that the patient will seek and receive dental care.
