Sensitive or swollen gums during pregnancy

Pregnancy is an exciting time, but it can cause uncomfortable if not painful symptoms at times. Sometimes pregnancy can be associated with gum problems, like bleeding gums and it’s important that any gum problems are addressed as soon as possible so that they do not get worse.

To avoid any discomfort or long-term issues due to sensitive gums during pregnancy, there are several actions you can take. Here are a few dental tips for pregnant women, which will be particularly helpful if you have sensitive or swollen gums while pregnant.

Why are my gums sensitive during pregnancy? 

One of the major reasons for changes in oral health during pregnancy is hormonal fluctuations, which can make your gums more sensitive to plaque, resulting in swollen or sensitive gums1. It is also thought that pregnancy might disrupt the natural balance of bacteria in your mouth, which could also have an impact on the health of your gums.2

Dental care tips for pregnant women

It can be uncomfortable to experience sensitive gums or swollen gums during pregnancy. You may also notice changes like bleeding gums. If you notice any changes, be sure to schedule an appointment with your dentist for a check-up, and he or she will be able to assess the issue and give you advice on the best way to deal with it.

Remember to take steps to ensure good oral hygiene when you are pregnant. 

  • Brush. During pregnancy, your sense of smell and taste may be heightened. Make sure to brush your teeth at least twice a day. Zendium toothpaste has a mild taste and is clinically proven to improve gum health*. It is also a SLS free toothpaste to respect the delicate tissues in your mouth and is clinically proven to be 4 times kinder than a regular toothpaste with SLS**. A sensitive toothbrush can also be a good addition to your oral hygiene routine, as its extra-soft bristles will be extra-gentle on your gums.
  • Floss. It’s also important to floss regularly, as this helps remove any food stuck between your teeth that can cause plaque or make your gums more sensitive or irritated. Try to floss once per day.

  • Use mouthwash. Mouthwash can help freshen your breath, and an alcohol-free mouthwash like Zendium can make your mouth feel less dry too, while helping prevent the causes of gum problems.
  • If you smoke, try to stop. In addition to the risks that smoking can pose to you and your baby, smoking can also be detrimental to your oral health, and can exacerbate any gum problems.

While pregnant, it is more important than ever to stick to a good daily oral hygiene routine.
