If you are weighing up IVF and dental treatment, the working rule is to finish anything that needs doing before a stimulation cycle starts, keep routine cleaning and check ups going during the cycle, and never sit on pain or infection at any stage. More than 103,000 assisted reproductive technology cycles were performed in Australia in 2023, according to the ANZARD report produced by the National Perinatal Epidemiology and Statistics Unit at UNSW. That is a lot of people asking their dentist the same questions, usually in a hurry, usually the week before a transfer.
Most dental care sits comfortably alongside fertility treatment. The reason to plan it is not danger. It is that a stimulation cycle is a demanding few weeks, and nobody wants an abscess competing for attention in the middle of it.
Key takeaways
- Dental x rays are aimed at the head and the dose is tiny. A single intraoral film delivers roughly 1 to 10 microsieverts, against an Australian background dose of about 1,700 microsieverts a year.
- Essential dental treatment under local anaesthetic has been studied during pregnancy and was not linked to worse outcomes.
- The widely quoted claim that gum disease adds two months to the time it takes to conceive comes from one Australian observational cohort. It has not been replicated, and no trial shows that treating gum disease helps anyone conceive faster.
- Book your check up, clean and any known fillings before egg collection, not after.
- Pain relief and antibiotics both have safer and less safe options around conception, so tell the dentist you are in a cycle.
- Swelling, fever or a tooth that keeps you awake is treated on its own timetable.
How common assisted reproduction is in Australia
The ANZARD report on assisted reproductive technology in Australia and New Zealand for 2023, released in September 2025, counted 103,556 cycles in Australia, up 3.5 percent on the year before, and 9,151 cycles in New Zealand. More than 20,000 babies were born following treatment across both countries that year. Around 6.3 percent of all women who gave birth in Australia in 2023 had used assisted reproduction.
More than one third of women achieved a live birth in their first ever complete cycle, counting the fresh transfer and any frozen transfers from the same egg collection. A complete cycle is not one appointment. It can run over months, so treating your mouth as something to sort out afterwards can mean waiting a long time.
In practice, the patients I see most often have already booked egg collection and have suddenly remembered a tooth that has ached on and off since last year. That is fixable, but far easier with three weeks of room in the diary rather than three days.
Dental x rays, with the actual numbers
ARPANSA, the Australian Radiation Protection and Nuclear Safety Agency, puts a single intraoral dental film, whether a periapical or a bitewing, at roughly 1 to 10 microsieverts. A panoramic image, the wide one that captures both jaws, sits at roughly 3 to 40 microsieverts. Average natural background radiation in Australia is about 1.7 millisieverts a year, which is 1,700 microsieverts, and Australians receive a similar amount again on average from medical imaging of all kinds.
So a single small dental film is a fraction of one percent of the radiation you absorb from the ground, the air and the sky in a year. The beam is collimated, meaning it is shaped down to a narrow field, and it is pointed at your jaw. The ovaries and uterus are nowhere near it. Modern doses are low enough that lead aprons are no longer routinely required, and the Australian Dental Association has adopted the ARPANSA code.
Images are still only taken when the answer will change what happens next. If a picture will not change the plan, it can wait. If the dentist needs to know whether a tooth has an abscess at the root, the image is the fastest way to stop guessing.
Does gum disease affect fertility
Search for this and you will find fertility clinic blogs stating that gum disease makes conception take two months longer. The figure is real. It deserves a description rather than a headline.
It comes from Hart and colleagues, published in Human Reproduction in 2012, using the Western Australian SMILE cohort. Women with periodontal disease took a median of seven months to conceive, compared with five months for women without it. The authors also reported that non Caucasian women with periodontal disease were the most affected subgroup and were more likely to take over 12 months.
Why the number needs a caveat
The cohort was made up of women who were already pregnant. Everyone in it conceived, so women who never did are absent from the data. Time to conception was recalled rather than measured as it happened, and the finding has not been replicated. Later reviews, including work published in Oral Diseases in 2022, describe the association as plausible but unproven.
The part worth underlining is this. No randomised trial has shown that treating gum disease shortens the time to conception, improves fertility, or raises the success rate of assisted reproduction. Anyone telling you otherwise is well ahead of the evidence.
That does not make gum treatment pointless. Gum disease is worth treating because it causes bleeding, bad breath, recession and eventually tooth loss, and those are good enough reasons on their own. If you want the detail on how gingivitis progresses and what treatment involves, we cover it in the stages of gum disease. Hormonal changes also make gums more reactive once you are pregnant, which is a separate issue covered in pregnancy gingivitis.
A timing plan you can actually use
Here is how I would sequence dental care around a cycle. It is a planning guide rather than a set of rules, and your fertility specialist has the final say on your own timing.
| Do this before you start a cycle | Fine to have during a cycle | Can usually wait until later |
|---|---|---|
| Full examination and any needed x rays | Scale and clean, and gum maintenance visits | Teeth whitening |
| Scale and clean, plus gum treatment if you have bleeding or deep pockets | Emergency care for pain, swelling or a broken tooth | Veneers, cosmetic bonding and smile design |
| Fillings for any decay already found | A simple filling if a tooth becomes symptomatic | Elective replacement of old but sound fillings |
| Root canal treatment or extraction of a tooth already known to be a problem | A temporary dressing to settle a tooth until after transfer | Orthodontic starts, unless you have already begun |
| Wisdom teeth that have flared up more than once | Adjusting a night guard that has stopped fitting | Implant surgery and bone grafting |
The left hand column removes predictable problems from your calendar. The middle column exists because you are not banned from the dental chair once a cycle starts. There is no evidence behind any rule about waiting a set number of days after a transfer before having a filling.
Local anaesthetic, painkillers and antibiotics
Numbing
Lignocaine 2 percent with adrenaline is usually described as the best balance of safety and effectiveness around pregnancy, and it is the standard agent in most Australian practices anyway. A safety analysis by Michalowicz and colleagues, published in the Journal of the American Dental Association in 2008 from the Obstetrics and Periodontal Therapy trial, found essential treatment including fillings and extractions under local anaesthetic during pregnancy did not increase adverse outcomes.
Pain relief
Paracetamol is the usual first choice while trying to conceive. Anti inflammatories such as ibuprofen sit in a more interesting position. Prostaglandins are involved in follicle rupture, and older controlled work found that follicles failed to rupture in about 10.7 percent of untreated cycles, roughly 50 percent of cycles with azapropazone, and up to 100 percent with indomethacin taken across the ovulatory window. A separate observational series reported 35.6 percent with continuous anti inflammatory use versus 3.4 percent without.
Those are striking numbers, and they are the reason this topic gets overstated online. The drugs studied were indomethacin and azapropazone at continuous dosing, not two ibuprofen tablets after a filling. A prospective controlled study published in Reproductive BioMedicine Online in 2024 found ibuprofen delayed triggered ovulation by a few hours without stopping it. Ibuprofen does not cause infertility. Preferring paracetamol around ovulation is still sensible. We compare the two in ibuprofen versus paracetamol for tooth pain.
Antibiotics
Tetracyclines, including doxycycline and minocycline, are avoided in women who may be pregnant, because from roughly the second trimester they can cause permanent discolouration of a developing child's teeth. Other options exist, so tell the dentist where you are in your cycle before a prescription is written. Antibiotics also do not fix a dead nerve. They are a holding measure.
The parts nobody warns you about
Three things come up repeatedly and none of them is well quantified.
Clenching is the first. Fertility treatment is stressful, and clenching is a common way stress shows up in the mouth. Patients describe sore jaw muscles, temple headaches, or teeth that feel bruised. I am not aware of any Australian data measuring this during stimulation cycles, so treat it as a pattern to watch for rather than a proven effect.
Gum sensitivity is the second. Oestrogen and progesterone effects on gum inflammation are well described in pregnancy and across the menstrual cycle. There is very little data specific to stimulation cycles. Gums that bleed more than usual during a cycle usually had existing inflammation the hormones have amplified.
Nausea is the third. If you are being sick, rinse with water rather than brushing straight away, because brushing softened enamel removes more surface than it cleans.
How this article differs from our pregnancy guides
Dental x ray safety during pregnancy and our dental care during pregnancy guide both cover what is safe once you already have a positive test, trimester by trimester. This article covers the earlier problem of planning treatment around a stimulation cycle, when you are not pregnant yet and want the mouth sorted before you are.
Common questions
Can I go to the dentist while doing IVF?
Yes. Examinations, cleans and simple treatment are all reasonable during a cycle, and urgent problems are treated whenever they happen. Tell the practice you are in a cycle so appointments can be timed around your scans and collection.
Are dental x rays safe if I am trying to get pregnant?
A dental x ray is aimed at your jaw, is tightly collimated, and delivers roughly 1 to 10 microsieverts for a small film. Your ovaries sit well outside the beam, and Australians absorb about 1,700 microsieverts a year from background sources alone. There is no evidence that dental imaging harms eggs, embryos or fertility.
Can I have a filling before embryo transfer?
Usually yes, and it is better done before transfer than left to deteriorate. A simple filling with local anaesthetic is a short appointment. If the tooth is borderline and causing no symptoms, a dentist may place a temporary dressing and finish afterwards, which is a scheduling decision rather than a safety one.
Does gum disease affect fertility?
One Australian observational cohort found women with periodontal disease took a median of seven months to conceive rather than five. It was based on women who were already pregnant, relied on recalled timings, and has not been replicated. No trial has shown that treating gum disease improves fertility or the success of assisted reproduction. Treat your gums because gum disease damages gums and teeth, not because of a fertility promise.
Can I take ibuprofen for toothache while trying to conceive?
Paracetamol is the more straightforward choice around ovulation. The concerning studies used continuous indomethacin and azapropazone rather than occasional ibuprofen, and a 2024 controlled study found ibuprofen delayed triggered ovulation by hours without preventing it. Get the tooth looked at rather than relying on tablets.
Getting the mouth sorted before you start
If a cycle is coming up, the most useful appointment is an ordinary one. An examination, any images that will change the plan, a clean, and a written list of what needs doing and in what order. Most people find there is less to do than they feared.
The team at Lumi Dental sees patients at Melrose Central in Melrose Park, Monday to Saturday, with Sunday available by appointment. New patients can book using the new patient special, and if you would rather ask a question first you can contact the practice or read about general dental care at Melrose Park. Lumi Dental does not provide general anaesthetic, and treatment that would need it is referred; sedation options are described on our IV sedation page.
