Learn to recognise early warning signs of common dental issues like gum bleeding, swelling, bad breath, and tooth sensitivity to ensure prompt professional care.
Dental health problems, such as gum disease and tooth decay, are caused by the buildup of bacteria and plaque. While many diseases start without pain, noticing early warning signs is crucial for effective and early treatment. This section describes the common symptoms, progression of disease, and the factors that increase your risk of developing severe, long-term dental issues, such as losing the bone that supports your teeth.

Dental disease refers to any chronic infection or damage to the gums, teeth, or bone in the mouth. It starts when bacteria and plaque are not removed completely, irritating the gum tissue and slowly causing decay or bone loss. If untreated, minor issues can become severe, often leading to tooth loss.
Dental problems often progress in stages:
Tooth decay (cavities) is another common issue caused by plaque acids eating away at the hard outer layer of the tooth (enamel). If decay is caught early, it can be treated with a simple filling. If ignored, the decay moves deeper into the tooth’s sensitive centre, causing pain and requiring more complex treatments like root canals.
The primary and most common cause of most dental disease is the sticky, colourless film called plaque. Plaque is made up of living bacteria that constantly form on your teeth. When plaque is not removed completely by daily brushing and flossing, it hardens into calculus (or tartar). Calculus cannot be removed by brushing and requires professional cleaning.
Several factors significantly increase your chance of developing or worsening dental disease:
Since dental disease can progress slowly and often without major pain, noticing these early warning signs is vital for prompt treatment. Do not ignore these subtle changes in your mouth, as they indicate active disease that is causing damage.
These signs indicate active irritation or damage in the mouth:
When the disease advances, the destruction of the bone supporting the teeth or the tooth structure causes more severe signs:

While most dental problems develop slowly, some underlying risks cannot be controlled, and certain symptoms require immediate attention.
Contact your dentist immediately or seek emergency care if you experience:
The general warning signs of dental problems include gums that bleed easily when brushing or flossing, persistent bad breath, new or increased sensitivity to hot or cold, and pain when chewing or biting down. Any of these should prompt a visit to the dentist.
Individuals who smoke or use tobacco are at the highest risk. Others at high risk include people with uncontrolled diabetes, those who consume frequent sugary foods, and people who don’t practice consistent daily brushing and flossing.
Core dental symptoms (cavities, pain, gum bleeding) are similar for everyone. However, hormonal fluctuations in women (during pregnancy or menopause) can increase gum sensitivity and swelling, making them more vulnerable to temporary or chronic gum issues.
The most impactful lifestyle factors are smoking/tobacco use, poor daily flossing, and frequent consumption of sugary or acidic foods and drinks. These habits directly fuel the bacteria that cause decay and gum inflammation.
While cavities and gum disease are directly caused by bacteria, yes, you can inherit a genetic predisposition. This means you might inherit factors like soft enamel, misaligned teeth that trap food easily, or an immune system that reacts aggressively to plaque, leading to faster tissue or bone loss.
