As an expectant mother, you’re probably prepared to experience the changes your body has to undergo. From morning sickness to swollen ankles, there always seems to be something new to prepare for. But what causes a toothache during pregnancy?

- Hormonal Changes
The surge of pregnancy hormones estrogen and progesterone impacts the health of your teeth and gums. These shifts can make your gums more sensitive and prone to swelling, bleeding and infection — a condition known as pregnancy gingivitis that affects 60%-70% of expecting mothers. This can cause pregnancy toothaches.
Hormonal changes also cause your body’s blood volume to increase by up to 50%, intensifying sensations throughout your body. While this is essential for fetal development, it can cause the gums to swell, which manifests as a throbbing sensation.
With inflamed gums, brushing and flossing become painful, tempting you to forgo them. They also bleed easily, which can lead to more bacterial buildup. This, in turn, triggers inflammation and even tooth pain. Without proper care, pregnancy gingivitis may progress to more severe gum disease, causing more toothaches.
- Changes in Diet and Cravings
Many pregnant women crave sugary or starchy foods that can stimulate the growth of cavity-causing bacteria. Sugars feed them, which produces acids that erode tooth enamel. Without it, your teeth become more sensitive, raising the chance of pain.
- Morning Sickness
Frequent vomiting due to morning nausea erodes enamel over time, leaving teeth more vulnerable to cavities and sensitivity. It can also irritate gums.
- Dry Mouth
Pregnancy-related nausea, vomiting and hormonal changes decrease saliva production. Saliva helps neutralize acid and wash away food particles, so a dry mouth puts you at higher risk for tooth decay and gum disease.
- Poor Oral Hygiene
Between the fatigue of growing a tiny human and the inconvenience of morning sickness, maintaining a thorough oral hygiene routine can fall by the wayside for some. This can allow plaque and bacteria to accumulate, resulting in cavities, gum disease and toothaches.
- Calcium Deficiency
As your body prioritizes calcium for your baby’s development, your teeth might be affected if you’re not getting enough. Low calcium can weaken tooth’s enamel, making them more vulnerable to decay and pain. You may want to increase your intake of calcium-rich foods like leafy greens, almonds and dairy products.
However, it’s best to consult your health care provider before making dietary changes or taking supplements. They will guide you on the safest approach to meeting your calcium needs.
The Importance of Regular Dental Checkups
Routine dental care is crucial, especially during pregnancy. Dentists are the professionals you see for regular six-month checkups, such as teeth cleaning and polishing, or when you have a toothache.
Some studies suggest links between poor dental health and possible complications like preeclampsia or low birth weight. This is why pregnant women are encouraged to schedule regular visits to the dentist. They can identify issues like gum disease and tooth decay early on before they develop into more complicated conditions.
Safe Home Remedies for Tooth Pain During Pregnancy
If you’re dealing with unbearable tooth pain while pregnant, home remedies can offer some relief. Here are a few gentle, pregnancy-friendly options to consider:
- Rinse in salty water: Add a teaspoon of salt to 8 ounces of lukewarm water and swish it in your mouth. If you have hydrogen peroxide, consider adding it. This saline mixture helps reduce inflammation and kill bacteria.
- Cold compress: Apply a cold compress to the outside of your cheek for at least 10 minutes to numb the area and reduce swelling. This can be especially helpful for gum pain.
- Proper hydration: Drinking plenty of water can help stimulate saliva production, neutralizing acid and washing away food that could instigate tooth decay.
- Good oral hygiene: Even when you’re exhausted, try to maintain a consistent oral hygiene routine. Brush your teeth twice daily, floss daily, and use an antibacterial mouthwash to keep plaque and bacteria at bay. You can also try using toothpaste formulated for sensitive teeth.
- Avoid trigger foods: Sugary, acidic or crunchy foods and beverages can aggravate sensitive teeth. Instead, opt for softer, gentler options like smoothies, yogurt, and cooked vegetables.
Can I Have a Pregnancy Toothache After a Miscarriage?
Yes, it’s possible to experience pregnancy-related toothache after miscarriage. This is because your body retains pregnancy hormones for up to 8 weeks, depending on how far along you were.
When this happens, it’s still best to visit the dentist and explain your situation. These professionals are qualified to recommend the best course of action to alleviate the discomfort and improve your oral health.
Also, consider reaching out to organizations that help grieving women overcome this type of loss like Untold Stories to hold your hand as you work through your loss. Additionally, consult a skilled therapist who specializes in maternal mental health to help you on this journey. They’ll also help determine whether you’re in the right head space when you decide to try to conceive again.
You Can Tackle Your Pregnancy Tooth Pain
While pregnancy toothaches can be incredibly uncomfortable, they’re also a normal part of the experience for many. If you need someone to talk to or walk with you through the changes you’re experiencing, reach out to a certified therapist to provide tailored support to boost your mental health.
Before you know it, your beautiful bundle of joy will be here and all this temporary tooth trouble will be a distant memory. So, hang in there, mama!
