Dental Care Before Radiotherapy in Stockholm – Oral Health Assessment Before Cancer Treatment
Dental care before radiotherapy is especially important when radiation will involve the head and neck. Dental infections, teeth with a poor prognosis, dry mouth, mucosal problems and future healing need to be assessed early so dental treatment can be coordinated with cancer care.
At Gloss & Floss in Södermalm, we can assist with general dental assessment, radiographs when indicated, treatment of dental infection, preventive planning and follow-up. If your oncology team has arranged referral to hospital dentistry or specialist dental care, that pathway should be followed and prioritised.
Important: follow the oncology care pathway
The Swedish national head-and-neck cancer care programme recommends dental-status assessment before radiotherapy or cytostatic treatment by a dentist or oral/maxillofacial surgeon working within hospital dentistry. Gloss & Floss can complement this with general dental care and preventive follow-up when appropriate, but does not replace coordination by your oncology team or hospital dental service.
Do you need a dental assessment before radiotherapy?
If head and neck radiotherapy is planned, dental assessment is often time-sensitive. Arrange it as early as possible and bring your treatment plan, expected start date, medication list and information about any hospital-dentistry referral.

Why is dental care needed before head and neck radiotherapy?
Infection in teeth, periodontal tissues or the jaw can become more difficult to manage when the body is undergoing cancer treatment. Head and neck radiotherapy can also affect salivary glands, oral mucosa, jawbone, mouth opening and healing. For these reasons, oral health should be assessed before treatment begins.
The Swedish national care programme specifically recommends dental-status assessment before radiotherapy or cytostatic treatment and emphasises optimal oral hygiene and dental-hygienist follow-up during and after treatment.
Quick overview
- Before treatment: dental examination, radiographs when needed, infection control, fluoride planning and assessment of teeth with uncertain prognosis.
- During treatment: support for dry mouth, mucosal symptoms, caries risk, infection signs and oral-hygiene difficulties.
- After treatment: long-term monitoring of saliva, caries, periodontal health, mucosa, trismus and the need for cautious surgical planning.
- Key point: dental treatment in a previously irradiated jaw requires individual risk assessment.
What does dental clearance before radiotherapy mean?
Dental clearance does not mean that every patient receives the same treatment or that teeth are removed routinely. The aim is to identify infection and teeth with a poor prognosis that may create problems during or after cancer treatment.
Depending on the findings, care may include caries treatment, assessment of previously root-treated teeth, periodontal treatment, extraction when a tooth cannot be safely maintained, fluoride prevention and a clear oral-hygiene plan.
Dental infection
We assessCaries, apical infection, previous root treatment, pain and swelling.
Why it mattersUntreated infection can cause acute problems during cancer treatment.
Periodontal health
We assessBleeding, periodontal pockets, calculus, mobility and active inflammation.
Why it mattersActive disease and teeth with poor prognosis may need treatment before major medical therapy.
Teeth with poor prognosis
We assessWhether a tooth can be predictably maintained in the relevant risk area.
Why it mattersExtraction after jaw irradiation can require greater caution.
Saliva and caries risk
We assessExisting dry mouth, caries activity, diet, fluoride needs and ability to maintain hygiene.
Why it mattersReduced salivary function can markedly increase caries risk.
Oral mucosa and mouth opening
We assessUlcers, irritation, suspected fungal infection, trismus risk and practical cleaning ability.
Why it mattersOral-care routines may need adaptation when tissues are sore or mouth opening is reduced.
How the dental assessment works
The assessment is adapted to your diagnosis, planned cancer treatment and timetable. If treatment is due to start soon, measures affecting infection risk and safety are prioritised.
Review of your medical situation
We review the planned cancer treatment, expected start date, medications, symptoms and previous dental care.
Clinical dental examination
We assess teeth, restorations, gums, oral mucosa, hygiene, infection signs and dental prognosis.
Imaging when indicated
Dental radiographs and, when clinically justified, dental imaging may support the assessment of roots, jawbone and hidden infection.
Management of infection and risk
Caries, root infection, periodontal disease or teeth with poor prognosis are prioritised according to urgency and the oncology timetable.
Preventive plan
Fluoride, oral hygiene, dental-hygienist support, saliva management and follow-up are planned according to risk.
Ongoing follow-up
After treatment starts or finishes, recall is adjusted according to saliva function, caries risk, tissue condition and your medical situation.
Timing: when should dental treatment be completed?
Dental assessment should take place as early as possible after head and neck radiotherapy is planned. If a tooth needs to be removed, the procedure should be scheduled early enough for adequate healing before radiotherapy. There is no single interval that is appropriate for every patient.
Timing depends on the radiation field, treatment start date, wound healing, infection risk and the oncology plan. Cancer treatment should never be postponed by the patient on their own initiative for dental treatment. When time is limited, the dentist and oncology team need to prioritise together what is essential before treatment and what can safely wait.
Oral health during cancer treatment
During head and neck radiotherapy, and sometimes during intensive systemic cancer treatment, the mouth may become more sensitive. Possible problems include mucositis, soreness, altered taste, thick or reduced saliva, fungal infection, increased caries risk and difficulty maintaining oral hygiene.
Dry mouth
Reduced or altered saliva can affect comfort, swallowing, speech and caries risk.
Sore oral tissues
Mucositis and irritation can make brushing, eating and swallowing more difficult.
Caries risk
Low saliva and dietary changes can accelerate tooth decay, making fluoride and preventive care important.
Mouth opening
Jaw stiffness or trismus may make eating and oral hygiene more difficult and can require multidisciplinary support.
Long-term dental care after radiotherapy
Oral-health effects can persist long after radiotherapy. Follow-up therefore needs to be risk-based rather than limited to the treatment period. The national care programme recommends dental-hygienist follow-up during and after treatment.
| Area | What may need follow-up | Related information |
|---|---|---|
| Dry mouth | Saliva, comfort, oral mucosa and caries risk. | Dry mouth |
| Caries prevention | Fluoride plan, new lesions and high-risk tooth surfaces. | Fluoride treatment |
| Periodontal health | Bleeding, pockets, calculus and oral hygiene. | Periodontal treatment |
| Dental hygiene | Individual professional cleaning and preventive support. | Dental hygienist treatments |
| Future surgery | Extraction, implant or other surgery requires careful planning in a previously irradiated area. | Oral surgery |
Implants and surgery after radiotherapy
Dental implants may be possible in selected patients after radiotherapy, but this is not routine planning. Radiation dose and field, bone quality, healing, time since treatment, medical history and the treating team’s recommendations all need to be considered. Alternative prosthetic solutions may sometimes be safer or more appropriate.
Dental support and cost questions in Sweden
Dental care that is directly linked to head and neck radiotherapy may, in some circumstances, be covered by regional Swedish rules for dental care as part of disease treatment. Which procedures are included, what patient fee applies and which provider may deliver the care depend on referral, regional decision and the care pathway.
Gloss & Floss can help you understand what documentation may be needed and direct you appropriately, but we cannot promise regional reimbursement or healthcare-level patient fees before eligibility and provider requirements have been confirmed.
For official Swedish information, see 1177: dental care related to certain diseases and disease treatments.

Frequently asked questions about dental care before radiotherapy
Why should I see a dentist before head and neck radiotherapy?
Dental infections and teeth with a poor prognosis can become difficult to manage during or after cancer treatment. Early dental assessment helps identify infection risks, plan necessary treatment and establish preventive oral care before therapy starts.
What does dental clearance before radiotherapy mean?
Dental clearance means assessing the teeth, gums, oral mucosa and jaws for infection and other risks before cancer treatment. It may include treating caries or periodontal disease, reviewing root-treated teeth, removing a tooth when prognosis is poor and planning fluoride and oral-hygiene support.
When should a tooth be removed before radiotherapy?
Teeth are not removed routinely. Extraction is considered when prognosis is poor or infection risk is high in a relevant area. If removal is necessary it should be planned as early as possible so adequate healing can occur before radiotherapy. Exact timing must be coordinated with the oncology team.
What happens if a dental infection is still present when cancer treatment starts?
An untreated infection may cause pain, swelling or an acute dental problem during a period when the body is already under significant treatment stress. This is why infections should be assessed and prioritised early.
How can head and neck radiotherapy affect saliva and caries risk?
Radiotherapy involving salivary glands can reduce saliva flow or change saliva consistency. Reduced saliva can markedly increase the risk of dry mouth, oral discomfort and rapid dental caries, so fluoride and preventive follow-up are often important.
What can help with dry mouth after radiotherapy?
Management may include frequent water intake, saliva-stimulating or saliva-substitute products, careful diet choices, daily fluoride according to an individual plan and regular professional follow-up. Advice should be adapted to your medical treatment and symptoms.
How often should I see a dental hygienist after radiotherapy?
There is no single interval for everyone. The Swedish national head-and-neck cancer care programme recommends dental-hygienist follow-up during and after treatment. Visit frequency should be individualised according to saliva function, caries risk, oral hygiene, periodontal health and recovery.
Can dental implants be placed after radiotherapy?
Sometimes, but implant treatment after jaw irradiation requires special risk assessment. Radiation dose and field, bone condition, healing, time since treatment, medical history and the recommendations of the treating care team all need to be considered.
Is dental care before radiotherapy urgent?
It is often time-sensitive. Dental assessment should be arranged as early as possible once head and neck radiotherapy is planned so necessary measures can be prioritised without unnecessary delay.
Can dental care related to radiotherapy be covered under Swedish healthcare-fee rules?
In some situations, dental care that forms part of treatment for disease may fall under regional Swedish rules and be charged similarly to healthcare. Eligibility depends on referral, diagnosis, regional approval and care pathway. Gloss & Floss cannot guarantee such coverage before eligibility is confirmed.
What should I bring to the dental appointment?
Bring your cancer-treatment plan or start date if available, medication list, information about the planned radiation field, contact details for your oncology team, previous dental records or radiographs if available, and any referral or certificate related to your treatment.
Do I need to go through hospital dentistry?
If your oncology team has referred you to hospital dentistry or specialist dental care, that pathway should be followed. The Swedish national care programme recommends dental-status assessment before radiotherapy or cytostatic treatment by a dentist or oral/maxillofacial surgeon working within hospital dentistry.
Can cancer treatment be postponed because of dental treatment?
Decisions about starting or changing cancer treatment must be made by the treating oncology team. Dental assessment should take place as early as possible so necessary dental measures can be prioritised without avoidable delay.
Is this page only relevant to radiotherapy?
The strongest dental recommendations on this page relate to head and neck radiotherapy. Some principles, such as infection control and oral-hygiene planning, may also be relevant before intensive chemotherapy or other cancer treatment, but the exact pathway should be determined by the oncology and dental teams.
Next step: arrange an oral-health assessment
If head and neck radiotherapy is planned, arrange dental assessment as early as possible. If you already have a referral to hospital dentistry or specialist care, follow that pathway first.
