Introduction
Many women spend considerable time preparing their bodies for pregnancy — reviewing nutrition, adjusting lifestyle habits, and speaking with their GP. Yet oral health is often overlooked during this important stage. If you are trying to conceive, you may not immediately think of visiting a dental hygienist, but pre-conception dental care is a genuinely important part of preparing for a healthy pregnancy.
Research consistently highlights a link between gum disease and complications during pregnancy, including preterm birth and low birth weight. Hormonal changes that begin in early pregnancy can also make existing dental problems worse, sometimes quite quickly. Addressing any underlying oral health concerns before conception may help reduce these risks and allow you to focus on your pregnancy with greater peace of mind.
This article explores why oral health matters for women trying to conceive, what to discuss with your dental hygienist, and how to maintain good oral health in the months before pregnancy. Professional dental advice is always recommended as individual needs vary significantly.
Featured Snippet: What Oral Health Steps Should Women Take Before Trying to Conceive?
Women trying to conceive are advised to attend a dental hygienist appointment for a professional clean and oral health assessment before pregnancy. Pre-conception dental care helps identify gum disease, cavities, or infection that may worsen during pregnancy due to hormonal changes. Establishing good oral hygiene habits early supports both maternal and foetal health outcomes.
Why Oral Health Matters When You Are Trying to Conceive
The connection between oral health and systemic health is well established. When bacteria from gum disease enter the bloodstream, they can trigger an inflammatory response throughout the body. For women who are trying to conceive or who are in early pregnancy, this systemic inflammation is particularly relevant.
Studies published in peer-reviewed journals have associated periodontal (gum) disease with an increased risk of preterm birth, pre-eclampsia, and low birth weight. Whilst the nature of this relationship is still being studied, the evidence is sufficient for dental and obstetric organisations to recommend that women address oral health concerns before or during early pregnancy.
Hormonal fluctuations associated with conception, early pregnancy, and throughout the trimesters can cause the gums to respond differently to plaque bacteria. This can make the gums more prone to swelling, bleeding, and sensitivity — a condition commonly called pregnancy gingivitis. By addressing any existing gum disease or plaque build-up before pregnancy begins, you give yourself a stronger foundation from which to manage these changes as they occur.
Pre-conception is also the ideal time to complete any dental treatment that might otherwise need to be delayed or modified during pregnancy, such as X-rays or certain clinical procedures.
How Hormonal Changes Affect Your Gums and Teeth
Understanding the dental science behind pregnancy-related oral changes can help you take the right preventative steps in advance.
During pregnancy, rising levels of oestrogen and progesterone alter how gum tissue responds to the bacteria found in dental plaque. Even a relatively small amount of plaque — an amount that might cause little noticeable irritation in a non-pregnant individual — can produce a heightened inflammatory response in someone who is pregnant. The gums may appear redder, feel tender, bleed more easily when brushed, and swell along the gum line.
This exaggerated response to plaque is not inevitable. It is largely driven by the bacteria present in the mouth at the time. If plaque levels are low and gum health is well established before pregnancy, the gums are far less likely to react significantly to hormonal changes.
There is also a condition called pregnancy epulis, which is a benign overgrowth of gum tissue that can develop in some women during pregnancy, often between teeth where plaque accumulates. This is generally harmless, though it can be uncomfortable. It is far less likely to develop in a mouth that is clean, plaque-free, and professionally maintained.
Some women also experience increased tooth sensitivity or erosion during pregnancy due to morning sickness. Stomach acid is highly erosive to tooth enamel. Understanding how to protect your teeth before these changes begin is an important part of pre-conception dental preparation.
What to Discuss at Your Pre-conception Dental Appointment
If you are trying to conceive and have not recently attended a dental hygienist appointment, booking one in the months before you plan to conceive is a worthwhile step. A professional hygienist appointment before pregnancy allows time to:
- Assess your current gum health and identify any early-stage gum disease (gingivitis or periodontitis)
- Remove tartar (calculus) and plaque build-up that home brushing cannot address alone
- Review your brushing and interdental cleaning technique to ensure it is effective
- Discuss any decay, sensitivity, or other dental concerns that might benefit from attention before pregnancy
- Provide tailored guidance on nutrition, fluoride use, and oral care products appropriate for the pre-conception period
It is worth mentioning to your dental team that you are trying to conceive, as this context helps them tailor their advice. For instance, they may recommend using a fluoride toothpaste of a specific strength, advise on safe whitening options (or those to avoid), and help you plan a schedule of dental visits throughout pregnancy.
A professional dental hygiene appointment at this stage is a practical and evidence-informed step you can take to support your oral health before pregnancy begins.
Gum Disease and Its Potential Impact on Pregnancy Outcomes
Gum disease exists on a spectrum. Gingivitis is the milder, reversible form, characterised by red, swollen gums that bleed when brushed. Periodontitis is the more advanced form, involving the loss of bone and connective tissue that supports the teeth. Both conditions involve bacterial infection and chronic inflammation.
The proposed mechanism linking gum disease to adverse pregnancy outcomes centres on the inflammatory response. Oral bacteria, particularly certain strains associated with periodontitis, can enter the bloodstream through inflamed gum tissue. Once in circulation, these bacteria and associated inflammatory markers may influence the uterine environment.
Some research has suggested that the oral bacteria Fusobacterium nucleatum, commonly found in periodontal disease, has been detected in the amniotic fluid and placenta of women who experienced preterm birth. Whilst this is an area of ongoing research, it underscores why dental professionals and midwives increasingly include oral health in pre-conception and antenatal guidance.
Treating gum disease before pregnancy does not guarantee any particular outcome, and individual results depend on many factors. However, entering pregnancy with healthy gums and a low bacterial load in the mouth is a sensible and evidence-informed goal.
Practical Oral Hygiene Habits to Establish Before Conception
Pre-conception is an ideal time to review and refine your daily oral hygiene routine. Building consistent habits now means they will be well established by the time pregnancy begins.
Brushing: Brush twice daily for a minimum of two minutes using a fluoride toothpaste. Research suggests that electric toothbrushes may offer advantages in plaque removal compared to manual brushes for some individuals, though technique is important with both. Brush gently at the gum line without applying excessive pressure.
Interdental cleaning: Brushing alone cleans only around 60% of tooth surfaces. Interdental brushes or floss should be used once daily to clean between the teeth and just below the gum line. Your dental hygienist can advise on the correct size of interdental brush for your teeth.
Diet: Reduce frequency of sugary or acidic foods and drinks. Frequent consumption is more damaging than occasional consumption. If you experience morning sickness in early pregnancy, avoid brushing immediately after vomiting — instead, rinse with water or a fluoride mouthwash and wait at least 30 minutes before brushing.
Fluoride: Use a toothpaste containing at least 1,450 ppm fluoride, as recommended by the NHS. Spit — do not rinse — after brushing to allow the fluoride to remain active on the teeth.
Hydration: Staying well hydrated supports saliva production, which plays a key protective role in neutralising acids and washing away food debris.
When to Seek Professional Dental Assessment
There are certain signs and symptoms that suggest a dental assessment would be beneficial, particularly when you are planning a pregnancy. Recognising these early and addressing them before conception is preferable to managing them during pregnancy, when some treatment options may need to be modified.
You may wish to seek a dental assessment if you notice:
- Gums that bleed regularly when you brush or use interdental tools
- Persistent bad breath despite good oral hygiene
- Gum swelling, redness, or tenderness around one or more teeth
- A tooth that has become sensitive to temperature or pressure
- Any visible changes to existing dental work, such as a loose filling or crown
- Mouth ulcers that do not resolve within two weeks
- Any swelling in the face, jaw, or neck — this should be assessed promptly
These signs do not necessarily indicate serious problems, but they do suggest that a clinical assessment would be beneficial. Early intervention is generally simpler, more comfortable, and more affordable than addressing issues that have progressed.

Nutrition, Supplements, and Oral Health Before Pregnancy
Nutritional choices in the pre-conception period can influence oral health as well as general health. Several key nutrients support gum tissue integrity, enamel strength, and the body's ability to resist infection.
Calcium and Vitamin D: Both are essential for maintaining bone density, including the alveolar bone that supports the teeth. Dairy products, leafy greens, fortified foods, and sensible sun exposure are important sources. If you are taking a pre-conception supplement, check that it includes Vitamin D.
Vitamin C: This nutrient supports collagen production, which is critical for gum tissue health. A diet rich in fresh fruits and vegetables provides adequate Vitamin C for most people.
Folic acid: Widely recommended for women trying to conceive to reduce the risk of neural tube defects, folic acid also plays a role in cell regeneration including oral tissues. The NHS recommends 400 micrograms of folic acid daily from the time you start trying to conceive until 12 weeks of pregnancy.
Sugar intake: Diets high in refined sugar increase the risk of dental decay. Reducing sugar consumption and increasing water intake benefits both oral health and general health, particularly as you prepare for pregnancy.
If you have any concerns about your nutritional intake and how it may relate to your oral health, your dental hygienist and GP can both provide relevant guidance.

Frequently Asked Questions
Is it safe to visit the dentist when trying to conceive?
Yes. Attending regular dental hygienist and dentist appointments when trying to conceive is not only safe but actively encouraged. Routine check-ups and professional cleans carry no risk to fertility or early conception. It is worth informing your dental team that you are trying to conceive so they can make informed decisions about timing for any radiographs or specific treatments. Early pregnancy is generally an ideal time to avoid elective dental procedures, so addressing any known concerns before conception is preferable.
Can gum disease affect my ability to conceive?
Some research has suggested a possible association between untreated periodontal disease and a longer time to conception, though the evidence is not definitive. The more established concern relates to pregnancy complications rather than conception itself. Regardless, treating gum disease before conception is beneficial for general and oral health and is consistent with good pre-conception care. A dental hygienist appointment is the appropriate starting point for assessing and managing gum health.
Will my gums definitely get worse during pregnancy?
Not necessarily. Many women experience some degree of gum sensitivity or bleeding during pregnancy due to hormonal changes, but this is not inevitable. The likelihood and severity of pregnancy gingivitis is closely linked to the level of plaque and tartar in the mouth at the outset. Women who enter pregnancy with low plaque levels and healthy gums may be less likely to experience pronounced gum problems during pregnancy, though individual responses to hormonal changes vary. Good oral hygiene and pre-conception professional care reduce the risk considerably.
Are dental X-rays safe when trying to conceive?
Dental X-rays use very low levels of radiation, and modern digital X-ray systems reduce this further. If you are actively trying to conceive and there is any possibility of early pregnancy, it is reasonable to inform your dentist so they can consider whether any X-rays are clinically necessary at that time. In most routine circumstances, X-rays can be safely taken during the pre-conception period. Your dentist will always apply the ALARP principle (as low as reasonably practicable) and use appropriate protective measures.
What dental treatments should I ideally complete before becoming pregnant?
The pre-conception period is a good time to address any outstanding treatment needs. This may include fillings for cavities, periodontal treatment for gum disease, replacement of failing dental restorations, or management of tooth sensitivity. Elective procedures such as teeth whitening are generally avoided during pregnancy, so if these are of interest, discussing them with your dental team before conception is appropriate. Any treatment plan should be based on your individual clinical needs following a professional examination.
Can morning sickness damage my teeth, and is there anything I can do beforehand?
Frequent vomiting associated with morning sickness exposes the teeth to stomach acid, which is highly erosive to tooth enamel. Over time, this can cause noticeable enamel erosion, sensitivity, and discolouration. There is no way to entirely prevent morning sickness, but you can prepare. Strengthening enamel beforehand through consistent use of fluoride toothpaste is beneficial. During episodes of vomiting, rinse with water immediately — do not brush straight away as enamel is temporarily softened by acid. Your dental hygienist can provide further guidance on protective strategies. You can also learn more about protecting tooth enamel and managing sensitivity on our blog.
Conclusion
Pre-conception dental care is an important but frequently overlooked aspect of preparing for pregnancy. Oral health and systemic health are closely connected, and entering pregnancy with healthy gums and a clean, well-maintained mouth provides a meaningful advantage as your body undergoes the hormonal and physiological changes of pregnancy.
Whether it is attending a professional hygienist appointment to remove tartar and assess gum health, refining your daily oral hygiene routine, or addressing any outstanding dental concerns before they become more complex, the steps you take now are genuinely worthwhile.
If you are trying to conceive, speaking with a dental hygienist about your oral health is a positive and proactive step. A dental hygiene appointment in London can provide a personalised assessment and help you prepare your oral health for the months ahead.
Pre-conception dental care and oral health advice for women trying to conceive should form part of a broader conversation about health and wellbeing before pregnancy. You do not need to have existing dental problems to benefit from professional guidance — prevention and preparation are the foundation of good oral health at every stage of life.
