Chapter 2: summary guidance tables for dental teams
Updated 10 September 2025
This guidance is issued jointly by the Department of Health and Social Care, the Welsh Government, the Department of Health Northern Ireland and NHS England, and with the support of the British Association for the Study of Community Dentistry.
Delivering Better Oral Health has been developed with the support of the 4 UK Chief Dental Officers.
While this guidance seeks to ensure a consistent UK-wide approach to prevention of oral diseases, some differences in operational delivery and organisational responsibilities may apply in Wales, Northern Ireland and England. In Scotland the guidance will be used to inform oral health improvement policy.
How to use these tables
These summary tables list the advice and actions that should be provided for all patients to maintain good oral health. They also outline the additional support that should be offered to people identified as being at higher risk of dental disease. Recent thinking suggests that all patients should be given the benefit of advice, care and support to improve their general and oral health, not just those thought to be at risk.
Patients giving concern are those at higher risk of dental disease, or for whom dental disease, or its management (such as requiring admission to hospital), would provide a significant challenge. They may include:
- children or adults presenting with current or past dental disease
- children with siblings who have dental caries experience
- children who have required dental treatment, including treatment under general anaesthetic or sedation, or whose siblings have done so
- children and adults with physical and learning disabilities
- children or adults who are medically compromised, for example those with diabetes
- mentally and physically frail older people including those with cognitive decline
- people undergoing treatments or therapies that place them at additional risk, for example some cancer treatments or drug therapy that results in dry mouth
- people who are homeless
- people who have contextual or environmental factors that may place them at additional risk, for example social disadvantage
- people with specific conditions that may place them at additional risk of disease in specific teeth, for example hypoplasia or retained impacted third molars
- people with vulnerabilities that would place them at additional risk from treatment, for example chemotherapy
Further details on assessing risk are outlined in chapter 1: introduction. Each patient鈥檚 risk needs to be assessed at every dental recall visit and monitored across the life course, as disease risk will change over time.
The grading of the quality (or certainty) of evidence and strength of recommendations in the following summary tables is based on . It reflects the extent to which the relevant disease-based Guideline Development Group (GDG)[footnote 1] is confident that desirable effects of an intervention outweigh undesirable effects across the range of patients for whom the recommendation is intended.
Recommendations may be:
- strong recommendations. The GDG is highly confident that desirable consequences outweigh undesirable or undesirable consequences outweigh desirable, typically based on high or moderate certainty evidence
- conditional recommendations. The GDG is less confident of the effectiveness of an intervention (low or very low certainty evidence) or the balance between benefits and harms is unclear
- good practice. Clinical opinion suggests this advice is well established or supported. No robust underpinning research evidence exists. Good practice points are primarily based on extrapolation from research on related topics and/or clinical consensus, expert opinion and precedent, and not on research appropriate for rating the certainty or quality of the evidence[footnote 2][footnote 3][footnote 4]
It is important to recognise that where a recommendation is conditional rather than strong, this does not mean that the intervention does not work but simply that the current evidence supporting it is not of the highest certainty.
The following tables provide evidence in relation to the prevention of dental caries, periodontal disease, oral cancer and tooth wear. Where appropriate, the tables provide advice according to age and/or specific risk factors.

Prevention of oral cancer
Use of tobacco, both smoked (for example cigarettes, pipes, waterpipes and shisha) and smokeless (for example paan, chewing tobacco and gutkha), seriously affects general and oral health. The most significant risk is for oral cancer and pre-cancers. The combined use of tobacco and alcohol further increases the risk of oral cancer. Encourage children and young people not to start smoking or using tobacco.
Use the Very Brief Advice (VBA) approach (ask, advise, act).
Table 3a: tobacco use in all adults and young people
| VBA step | 搁别肠辞尘尘别苍诲补迟颈辞苍听听听听听 | Strength of recommendation |
|---|---|---|
| Ask | At every opportunity, ask patients if they smoke and record smoking status (smoker, ex-smoker, never smoker) | 厂迟谤辞苍驳听 |
| Advise | Explain that a combination of behavioural support and the medication varenicline, or short-acting with long-acting Nicotine Replacement Therapy, are likely to be most effective. | Strong |

Table 3b: Smokeless tobacco use in all adults and young people
| VBA step | 搁别肠辞尘尘别苍诲补迟颈辞苍听听听听听 | Strength of recommendation |

| Ask | Ask patients if they use smokeless tobacco, using the names that the various products are known by locally. It may be helpful to show a picture of what the products look like (see chapter 11, figure 1).听听听聽 | Strong |
| Advise | If someone uses smokeless tobacco, ensure they are aware of the health risks and provide very brief advice.听听听 | Strong |
| Act | Refer patients who want to quit to specialist support services.听听听聽 | Strong |
Table 3c: alcohol use聽in all adults and young people
Regularly drinking more than 14 units of alcohol per week can adversely affect general and oral health, with the most significant oral health impact being the increased risk of oral cancer. The combined use of tobacco and alcohol further increases the risk of oral cancer.
Alcohol Identification and Brief Advice (IBA) uses the AUDIT-C tool (or similar) to ask and assess risk and provide advice.
| VBA step | 搁别肠辞尘尘别苍诲补迟颈辞苍听听听听听 | Strength of recommendation |
|---|---|---|
| Ask | Use the AUDIT-C tool (or similar) to assess a patient鈥檚 level of risk of alcohol harm by completing 3 consumption questions. | Strong |
| Advise | If AUDIT C score is 4 or below, give positive feedback and encourage your patient to keep their drinking at lower risk levels. If score is 5 to 10, give brief advice to encourage a reduction in alcohol consumption and reduce the risk of alcohol harm. |
Strong |
| Act | Feed back to the patient that their level of drinking is putting them at risk of developing a range of health problems (including cancers of the mouth, throat and breast) and this increases the more you drink and the more frequently you drink. Highlight 鈥榣ow risk鈥 guidelines for alcohol consumption from UK Chief Medical Officers: 鈥 to keep health risks from alcohol to a low level, it is safest not to drink more than 14 units a week on a regular basis 鈥 if you regularly drink as much as 14 units per week, it鈥檚 best to spread your drinking evenly over 3 or more days 鈥 if you wish to cut down the amount you drink, a good way to help achieve this is to have several drink-free days a week Give a 听听听 |
Strong |
| Act | For those who are pregnant or think they could become pregnant, the safest approach is not to drink alcohol at all, to remove the risk of alcohol-related harm to the baby. | Good practice |
| Act | AUDIT-C score of 11 or above, refer to GP or community specialist alcohol service.聽 | Good practice |

| Obtain an updated medical, social and dental history and perform an intraoral and extraoral visual and tactile examination for all patients at each oral health assessment visit. | Good practice |
| Where there is cause for concern, in line with national referral recommendations, patients should be referred on an urgent or suspected cancer pathway if they have any of the following: 鈥 an unexplained ulceration in the oral cavity lasting for more than 3 weeks 鈥 a persistent and unexplained lump in the neck 鈥 a lump on the lip (inner or outer) or in the oral cavity consistent with oral cancer 鈥 a red patch in the oral cavity consistent with erythroplakia 鈥 a red and white patch in the oral cavity consistent with erythroleukoplakia 鈥 persistent unexplained hoarseness 鈥 persistent pain in the throat or pain on swallowing lasting for more than 3 weeks |
