9 Reasons Why Your Gums Are Itchy
If your gums are itching, it is more than just a random irritation, it is often a sign that something is going on in your mouth. Whether it is plaque and tartar buildup, gum disease, or even an allergy to your toothpaste, there are a lot of potential causes. Hormonal changes, dry mouth, and even grinding your teeth can all contribute to the discomfort.
A quick visit to your dentist, like the team at South Ancaster Family Dental, can help identify the issue and put you on the path to relief.
- Plaque & Tartar Buildup
Plaque, a sticky film of bacteria, is one of the common causes of itchy gums. When plaque is not removed through regular brushing and flossing, it hardens into tartar, which further irritates the gums. This irritation often leads to itchiness and inflammation.
Unchecked plaque and tartar buildup create a breeding ground for bacteria, potentially causing gum infections and other oral health issues. Professional dental cleanings are essential for removing stubborn tartar, as at-home dental care alone is insufficient for addressing hardened plaque.
- Gum Disease
Itchy gums are a common symptom of gum disease, also known as periodontal disease. Early-stage gum disease (gingivitis) causes redness, swelling, and irritation in the gums. Left untreated, it can progress to periodontitis, a more severe condition that damages the gums and underlying bone structures.
Symptoms of gum disease often include:
- Persistent itchiness
- Bleeding gums
- Bad breath
Regular dental checkups, proper hygiene practices, and professional cleanings play a crucial role in preventing and managing gum disease effectively.
- Toothpaste Allergies
Sensitivity to certain ingredients in toothpaste can also lead to itchy gums. Common offenders include sodium lauryl sulphate (SLS), artificial flavours, and harsh whitening agents.
If you suspect your toothpaste may be the culprit, consider switching to a hypoallergenic or natural toothpaste. Look for products approved by dental associations in Canada, which indicate that toothpaste is both effective and safe.
- Bruxism
Bruxism, or teeth grinding, often occurs during sleep and is linked to numerous oral health concerns, including itchy gums. Grinding and clenching place undue pressure on the gums and teeth, leading to irritation.
Those diagnosed with bruxism should speak to their dentist about custom mouthguards to minimize grinding and protect the gums. Over time, addressing this issue can significantly improve oral health and reduce discomfort.
- Dry Mouth

Dry mouth, or xerostomia, can cause itchiness by reducing the production of saliva, which normally helps to clean the mouth and neutralize bacteria. Without sufficient saliva, bacteria accumulate, irritating both the gums and oral lining.
Common causes of dry mouth include certain medications, dehydration, and medical conditions such as Sjögren’s syndrome. Drinking more water, using a humidifier, or trying specific dry mouth products recommended by your dentist can help alleviate symptoms.
- Hormonal Changes
Hormonal fluctuations, such as those occurring during pregnancy, menopause, or menstruation, can affect oral health. Increased hormone levels can result in heightened blood flow to the gums, making them more sensitive and prone to irritation.
Pregnancy gingivitis is a well-documented condition that often leads to itchy, swollen gums. Maintaining an exemplary oral hygiene routine and scheduling regular dental visits can help manage gum health effectively during periods of hormonal change.
- Teething
Teething is a common reason for itchy gums in infants and young children. When teeth are erupting, the gums can become sore, swollen, and itchy.
Parents can alleviate their child’s discomfort by using teething gels, frozen washcloths, or silicone teething rings. While teething is normal, any excessive redness or prolonged discomfort should prompt a visit to a pediatric dentist to rule out complications.
- Tooth Abscess
A tooth abscess is a severe oral health issue where infection forms a pocket of pus near the tooth’s root. The buildup of infection often leads to swollen, itchy, and painful gums.
Symptoms of an abscess may also include fever, intense tooth pain, and swelling in the face or jaw. Immediate dental care is required to treat a tooth abscess, as untreated cases can lead to serious complications.
- Oral Hygiene
At its core, the connection between itchy gums and oral hygiene cannot be overstated. Failing to brush and floss effectively allows bacteria to thrive, irritating the gum tissue and contributing to plaque buildup.
Adopting proper oral hygiene, including brushing at least twice a day with fluoride toothpaste, flossing daily, and using antimicrobial mouthwash, is critical to maintaining gum health. Regular cleanings with dental professionals further ensure the removal of any hidden buildup.
