3 Ways Pregnancy Affects Your Oral Health

Pregnancy is an exciting time filled with changes. Some changes you may expect, such as a growing tummy or sudden cravings for pickles and ice cream. Other changes, however, may catch you by surprise, such as increased risk of nose bleeds, hot flushes and constipation.

Although you feel you can handle most of these developments on your own without batting an eye, keep in mind that some physical shifts may require outside help to resolve. Your dental health, for example, may need assistance from your dentist to stay in good condition.

As your pregnancy progresses, keep a lookout for the following problems. With a few minor adjustments in your lifestyle and a little help from a professional, you can ensure your teeth and gums remain healthy throughout each trimester.

1. Morning Sickness Eats Away at Enamel

Statistics estimate that nearly 75% of women experience morning sickness during pregnancy. Although some women merely feel queasy for a few weeks, many unlucky mothers may have to run to the toilet several times a day when the morning sickness gets the best of them.

Unfortunately, vomiting regularly wreaks havoc on your teeth in addition to inhibiting your nutrient absorption. Typically, stomach acid has a pH level of about 1.5 to 3.5, more than enough to eat away at your enamel.


Talk to your doctor about your morning sickness. He or she may recommend a combination of vitamins and dietary changes to ease the nausea and give you some relief.

If you still face regular morning sickness during your first trimester, you can minimise the damage to your teeth by rinsing with water after you vomit. Then, wait for 60 minutes before brushing your teeth. When you brush immediately after heaving, the bristles push the acids deeper into the grooves of your teeth.

2. More Frequent Meals Increase Sugar Exposure

Many doctors recommend that pregnant women eat small meals throughout the day. Regular healthy snacks not only ensure the mother receives adequate nutrition, but these foods also keep blood sugar levels in check, minimising nausea and energy crashes.

However, the more often you graze, the more sugar you put into your mouth. The sugar feeds oral bacteria, which in turn produce acids that eat away at your enamel. Furthermore, the constant food intake means your mouth doesn't have enough time to restore its natural, neutral pH levels, so your teeth sit in a constant acid bath.


As you 'eat for two', remember that some snacks are better than others for you, your baby and your smile. When you pick and choose your meals, look for foods with low sugar and high fibre content.

Leafy green vegetables, such as spinach and kale, contain folic acid which will boost your baby's neural development. Additionally, these veggies supply a healthy amount of calcium that will maintain your teeth and bones.

Cheese and yoghurt are also excellent snacks during pregnancy. These dairy items have plenty of protein for your baby's growing muscles, iron for your red blood cells and calcium for your teeth. Better still, cheese and yoghurt temporarily increase your mouth's pH levels, reducing your risk for cavities.

3. Hormone Fluctuations Trigger Gum Inflammation

During pregnancy, your hormone levels go wild. Your progesterone production skyrockets, which then stimulates the prostaglandin production. Prostaglandins regulate the female reproductive system, and they affect how your body responds to injury and illness. In some cases, prostaglandins cause inflammation of blood vessels, resulting in sensitive gum tissues and swelling.

Due to hormone fluctuations, many pregnant women have an increased risk of suffering from gingivitis and gum disease. In extreme situations, the swelling leads to a benign growth known as a pregnancy tumour, which bleeds easily.


Although you can't control your hormones, you can take steps to reduce inflammation. Take care to floss every night, and always brush with a soft-bristled brush. Avoid trigger foods that make your teeth feel more sore and sensitive, such as hot tea or cold ice cream.

Talk to Your Dentist About Your Pregnancy

While pregnancy leads to a variety of changes, these changes don't have to negatively impact your oral health. If you haven't already done so, set up an appointment with your dentist to discuss your pregnancy and ways you can maintain your teeth and gums over the next few months.

You've been to the dentist enough to know the basics — you're in and out after a quick cleaning, flossing and X-ray scan. But this time there was something different. Your dentist took a quick look at your gums, frowned and recommended that you get a surgery called a frenectomy sooner than later.

If you're like most people, you probably haven't ever heard of a frenectomy, and you're understandably a little frightened and confused by the recommendation. But frenectomies are actually minor surgeries that can go a long way towards preserving your teeth for decades to come.

Whether your dentist referred you to a gum specialist or has the know-how to perform a small frenectomy in-house, keep reading. We'll tell you what you can expect from this minor procedure.

In toddlers and young children, a loose milk tooth usually heralds the arrival of its permanent replacement. This is a time of discovery, a time to celebrate. Loose milk teeth eventually fall out, as nature intended, and are replaced with permanent teeth. However, there is nothing natural about loose teeth in adults. A loose tooth is an indicator that something is wrong.

Teeth are held in place, within their sockets, by the periodontal ligament. These web-like tissue fibres cover the roots of teeth and anchor them to the jawbone. Gum tissue also helps to hold teeth in place. If teeth are loose then, there is an underlying issue that is affecting those tissues.

Teeth whitening has come a long way over the last few thousand years. The ancient Egyptians whitened their teeth with ground pumice stone and wine vinegar 4,000 years ago. Later, the Romans decided that urine was their whitening agent of choice! It wasn't until the 1960s that peroxide, which is used to whiten teeth today, was used to whiten teeth.

Hydrogen and carbamide peroxide, the two main components of teeth whitening, can work wonders with stained teeth. What they cannot do, however, is whiten dental bridges or in fact any other type of dental restoration. Whitening agents simply cannot penetrate these materials in the same way they can natural teeth.

If your bridge needs to be whitened, you may be out of luck. However, if you get a bridge that is whiter than your natural teeth, you may be able to solve the problem by whitening your teeth to match. Learn more about your options below.

When you think about losing teeth, you may picture a gap-toothed grin on a wide-eyed child who's talking about the tooth fairy. For children, tooth loss allows for the permanent teeth to erupt properly.

But many adults experience tooth loss as well. As an adult contemplating tooth extraction, you may feel nervous or even embarrassed, so it's
important to understand the causes of adult tooth loss, possible prevention and common  types of tooth replacement .

In this blog, we list four facts about tooth extraction that can help you feel more prepared for this procedure.

In general, the typical shade of healthy teeth is an off-white hue with slight undertones of brown, yellow or grey. However, many people find that their teeth are much darker than off-white. If you're one of these people, you may be wondering why your teeth aren't as bright as everyone else's and what you can do about it.

Browning and yellowing teeth have a variety of possible causes. One of the most well-known is aging, but what about discolouration that happens before you reach your senior years? If you're an adult with stained teeth, there are two broad categories of tooth discolouration you should look to: extrinsic and intrinsic.

Both can be remedied in different ways, but the right solution will depend on which of these discolouration types is affecting you.
