Quick Reference: Best Days for Dental Work
- Rule of thumb: schedule dental work when the Moon is not in Aries (teeth), Cancer (jaw), or Pisces (lips), and ideally during the waning phase after the Full Moon.
- Best signs: Taurus, Gemini, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius.
- Avoid: the Full Moon day itself, plus 24 hours either side, for tooth extractions and oral surgery.
- Where the tradition comes from: 200 years of Farmers’ Almanac lunar-sign records. Same methodology as our other Best Days calendars.
How the Farmers’ Almanac Picks Best Days for Dental Work
The Best Days system rests on an old idea: the Moon’s position in the zodiac influences the body part governed by each sign. Aries governs the head and teeth. Cancer governs the jaw. Pisces governs the lips. Scheduling dental work in those signs (or right around the Full Moon) is traditionally believed to bring extra bleeding, sensitivity, or slower healing. The safer windows are the days when the Moon has moved on to another sign, ideally after the Full Moon, when the body’s fluids are in a waning phase.
Modern dentistry does not depend on lunar timing, but readers who follow the Best Days tradition find peace of mind in scheduling around it. Use the calendar below as a planning aid, not a substitute for your dentist’s guidance.

The current month is highlighted. Dates reflect the Moon’s position in the zodiac plus the waxing/waning phase, per Farmers’ Almanac methodology. Confirm treatment timing with your dentist, especially for scheduled surgery.
Why This Tradition Exists (and When Not to Follow It)
The lunar-sign method dates to European folk medicine and made its way into American almanacs in the 1800s. It was widely used by rural readers who scheduled everything, hair cuts, weaning, planting, dental work, around the Moon’s sign because it was the calendar they trusted. Modern research does not support a causal link between lunar phase and clinical outcomes, though a handful of small studies have looked at post-extraction bleeding around the Full Moon with inconsistent results.
Do not delay urgent dental care to wait for a Best Day. Infections, abscesses, uncontrolled bleeding, and severe pain need attention immediately. Use Best Days for planned work only, cleanings, cavity fillings, routine crowns, elective extractions, orthodontic milestones, and cosmetic work.
Best Days for Dental Work FAQ
What signs should I avoid for dental work?
Aries governs the teeth and head. Cancer governs the jaw. Pisces governs the lips and mouth. Traditional Best Days practice avoids scheduling dental work in any of these three signs.
Is the Full Moon really a problem for tooth extractions?
The tradition says yes, on the grounds that fluids and pressures in the body peak with the Full Moon and can worsen post-extraction bleeding. Clinical evidence is mixed but not zero. Most readers schedule elective extractions during the waning phase after the Full Moon to stay within tradition and give themselves peace of mind.
Are Best Days different for children’s dental visits?
The same lunar-sign guidelines apply. Some families additionally follow the tradition of avoiding the day of the New Moon for baby tooth extractions (the theory being fluids are at their lowest, delaying healing). Follow your pediatric dentist’s clinical guidance first.
Where do these dates come from?
The Farmers’ Almanac calculates the Moon’s zodiac sign and phase for every day of the year using the same lunar-position math we have used since 1818. The Best Days for Dental Work calendar cross-references the daily sign against the head-mouth-jaw signs and flags all other days as favorable, with the strongest windows in Taurus, Capricorn, or Aquarius during the waning phase.
Can I use these dates in Canada, the UK, or Australia?
Yes. The Moon’s zodiac sign is the same everywhere on Earth on a given date. Time-zone differences can shift a date at the edges (a sign that changes at 11:30 p.m. US Eastern will change at 4:30 a.m. UK), so for borderline days check your local time.
