Damien O’Brien MPSI provides an overview of dental and oral health, including common conditions and pain management in the pharmacy
Introduction
Dental health is an important component of overall health and wellbeing. Despite its importance, dental health is often overlooked until pain, discomfort or visible problems arise. The mouth can provide valuable insight into general health, with oral symptoms often reflecting underlying systemic disease, adverse effects of medication, or nutritional deficiency.
Oral health issues are a common presentation in community pharmacy, with patients often seeking advice
for toothache, mouth ulcers, dental infection, dry mouth, oral thrush, bleeding gums and denture-related problems. Pharmacists can play an important role in promoting good oral health and bridging the gap between dental health and general health.
Pharmacists are well placed to counsel patients on symptom relief, encourage preventive measures, identify warning symptoms, and guide patients towards appropriate referral where needed. This article will explore the principles of good dental care, outline common conditions encountered in community pharmacy, and examine the pharmacist’s role in supporting dental health.
Good dental care practices
Prevention is central to maintaining good dental health, with several daily habits being important in reducing the risk of dental problems. Effective oral hygiene is centred on regular toothbrushing with fluoride toothpaste. Patients should be advised to brush their teeth twice daily for at least two minutes with a fluoride toothpaste. This helps to remove plaque, reduce bacterial load and strengthen enamel. Patients should avoid rinsing their mouth after brushing, as this washes away fluoride and reduces its protective effect.
Brushing the tongue is also important in maintaining good oral health. Flossing helps to remove food particles and plaque from interdental spaces, where a toothbrush may not reach. Pharmacists may also guide patients towards appropriate mouthwash products,
with fluoride mouthwashes used for additional protection or short-term chlorhexidine products in certain cases.
Diet and lifestyle also have a significant influence on dental health. A balanced diet containing calcium, phosphate and vitamins is essential for maintaining dental health. Frequent consumption of foods and drinks high in sugar increases the risk of dental caries. It is often the frequency of sugar consumption, rather than quantity, that increases this risk.
Maintaining adequate hydration supports saliva production, which has a protective role through lubrication, buffering acids and controlling microbial growth within the mouth. Excessive alcohol consumption and smoking are risk factors for periodontal disease, oral cancers, delayed healing and dry mouth.
Finally, individuals should be encouraged to attend regular dental check-ups for professional cleaning and examination, which are essential for prevention, early detection and management of dental conditions.
Pharmacists can make an important contribution to oral health and help reduce the burden of dental disease by reinforcing these preventive measures during routine consultations.
Dental pain: Management in the pharmacy
Dental pain is a common presentation encountered in community pharmacy and may arise from a wide range of causes. Management of dental pain in pharmacy is focused on short-term analgesia while encouraging dental assessment where appropriate.
Paracetamol and non-steroidal anti- inflammatory drugs (NSAIDs) are the first-line treatment options for acute dental pain. NSAIDs are particularly useful where pain is accompanied by inflammation within the tooth or surrounding tissues. Pharmacists should consider contraindications and cautions with NSAID use, including gastrointestinal disease, renal impairment, anticoagulant use and other comorbidities.
Routine use of codeine-containing products is generally not recommended due to the limited additional benefit
in dental pain and the potential for adverse effects, misuse and dependence. Topical products may provide temporary symptomatic relief in some cases. However, patients should be counselled that analgesics do not address the underlying cause, and persistent pain should prompt dental assessment. Avoiding appropriate dental treatment can lead to complications such as infection, abscess formation or tooth loss.
Common dental conditions
There is a wide range of common dental conditions encountered in community pharmacy. Community pharmacists
are ideally placed to identify common presentations, provide appropriate advice and recognise when referral
is needed. Some of these common conditions are outlined below.
Dental caries
Dental caries, also known as tooth decay, is the progressive demineralisation of tooth enamel and dentine, caused by acids produced when oral bacteria metabolise sugars. It is one of the most prevalent diseases globally and is a major cause of dental pain and tooth loss. Insufficient fluoride exposure is an important contributing factor in the development of dental caries.
Symptoms may include pain, sensitivity and difficulty eating, while early caries may be asymptomatic. Complications may include inflammation of surrounding tissues, abscess formation and tooth loss. Preventive advice is important, including counselling on fluoride use, reducing the frequency of sugar intake, and maintaining good oral hygiene. Advanced caries typically requires dental intervention.
Maintaining adequate hydration supports saliva production, which has a protective role
Oral candidiasis
Oral candidiasis, also known as oral thrush, is another presentation often encountered in community pharmacy. It is a fungal infection that typically presents as white plaques in the mouth, often accompanied by pain, altered
taste or a burning sensation.
Some patients may experience erythematous, inflamed oral tissues.
Risk factors for oral candidiasis include recent antibiotic use, inhaled corticosteroids, diabetes, dry mouth, immunosuppression and poor denture hygiene.
Pharmacists can play an important role in identifying contributing factors and advising on both treatment
and prevention. Patients should be educated on maintaining good oral hygiene, using proper inhaler technique and rinsing the mouth after inhaler use to reduce the risk of developing oral candidiasis.
Topical antifungal therapy with nystatin or miconazole is typically sufficient to treat oral candidiasis. Miconazole is available over-the- counter, while nystatin is now available for supply by pharmacists under the Common Conditions Service. Oral antifungals, such as fluconazole, may be required in severe disease.
Mouth ulcers
Mouth ulcers are common self-limiting lesions of the oral cavity, often caused by local trauma, stress, nutritional deficiency or certain foods. They may cause discomfort and pain, particularly when eating or drinking. Identifying and avoiding triggers is an important preventive measure.
The objective of treatment is to relieve symptoms, decrease severity, promote healing, and prolong remission. Management of mouth ulcers is centered on symptomatic treatment, including protective pastes, topical analgesic preparations and topical corticosteroids. Mouth ulcers that persist, recur frequently or have an unusual appearance should be referred for further assessment.
Xerostomia
Xerostomia, commonly referred to as dry mouth, is another common presentation in community pharmacy. The main symptoms of xerostomia include mouth dryness, oral burning, difficulty swallowing and altered taste.
Saliva has an essential protective role in lubricating oral tissues, buffering acid and controlling microbial growth. Reduced saliva increases the risk of dental caries, oral infection, halitosis, swallowing difficulties and oral discomfort.
Xerostomia is particularly relevant in pharmacy practice as it is frequently associated with medication adverse effects. Medications such as anticholinergic agents, diuretics, antidepressants, antihistamines and antihypertensives may lead to xerostomia. Dehydration, cancer treatment and systemic conditions such as diabetes, thyroid disorders and autoimmune disease may also contribute to xerostomia.
Management may include reviewing contributory medicines and switching where appropriate. Non- pharmacological approaches that may improve symptoms include maintaining hydration, limiting caffeine and alcohol, avoiding smoking, and using sugar-free gum. Saliva substitutes may also be used to provide symptom relief.
Prescription medications such as pilocarpine may be considered under medical supervision, particularly in post- radiation xerostomia. Pilocarpine works by acting on muscarinic receptors and stimulating saliva production.
Gum disease
Gingivitis is characterised by inflammation of the gums, often presenting with redness, swelling, tenderness and bleeding during brushing or flossing. It is commonly caused by plaque accumulation at the gumline and is usually reversible with

improved oral hygiene. Professional scaling and short-term chlorhexidine mouthwash may be useful.
If left untreated, gingivitis may progress to periodontitis. Periodontitis is the more severe form of the disease, involving destruction of the supporting structures around the teeth and increasing the risk of tooth loss. This progression is associated with smoking, diabetes and poor oral hygiene, reinforcing the importance of preventive advice and early intervention.
Advanced periodontitis may require specialist periodontal treatment and, in selected cases, adjunctive antibiotic therapy. Antibiotics may be considered if there is evidence of spreading infection, systemic involvement, the person is immunocompromised or has uncontrolled diabetes.
Where antibiotics are indicated, metronidazole is commonly used at a dose of 400mg every eight hours for three days, extended to five days in cases of severe infection. Patients should be counselled to avoid alcohol while taking metronidazole. Amoxicillin may be considered where metronidazole is contraindicated or unsuitable.
Dental abscess
Dental infections, including localised abscesses, can range from contained infections to potentially serious disease. Abscesses typically present with severe throbbing pain, tenderness, local inflammation or a bad taste in the mouth. Facial swelling, fever, malaise or difficulty swallowing may indicate that infection has spread beyond local tissues and requires urgent assessment. Early identification and treatment are essential to prevent complications.
Dental abscesses are primarily treated with local measures through dental drainage and definitive management of the affected tooth where appropriate. Antibiotics should only be used as an adjunct to dental treatment in cases where local treatment is ineffective or where there is evidence of spreading infection or systemic involvement. Phenoxymethylpenicillin is generally considered first-line in these cases, with metronidazole considered in cases of penicillin allergy.
The role of the pharmacist
Pharmacists play an important role in supporting dental health through preventive measures, early recognition and appropriate management. As one of the most accessible healthcare professionals, pharmacists are often the first point of contact for patients with dental issues or those seeking advice on maintaining good dental health. This creates valuable opportunities for early intervention before progression to more severe disease.
Pharmacists can counsel patients on fluoride use, good oral hygiene practices, diet, limiting alcohol
intake and smoking cessation, all of which can improve long-term dental outcomes. Pharmacists also have the clinical expertise to recognise warning symptoms that may require referral.
Persistent oral ulceration, facial swelling, dysphagia, unexplained bleeding or severe pain should prompt urgent referral for dental or medical assessment. Furthermore, pharmacists can counsel patients on the appropriate use of medicines, including analgesics and antibiotics. By reinforcing preventive measures, recognising warning symptoms and providing evidence-based advice, appropriate treatment recommendations and patient education, community pharmacists can make a significant contribution to improving dental health outcomes.
