โรคฟันผุ: ปัญหาสุขภาพฟันที่ไม่ควรมองข้าม

What is Tooth Decay?

Tooth decay (Dental Caries) is the process in which the tooth structure is destroyed due to bacteria in the mouth producing acids that erode the tooth enamel. This process begins with plaque formation on the tooth surface. When it comes into contact with sugar from food and drinks, bacteria convert the sugar into acid, which weakens the enamel, leading to cavities. If left untreated, the decay can spread to deeper layers of the tooth and eventually reach the dental pulp, causing severe pain and potentially leading to tooth loss.

The Process of Tooth Decay

The progression of tooth decay occurs in four key stages:

1. Plaque Formation

Plaque is a layer of bacteria that forms on the tooth surface and gums. If oral hygiene is inadequate, plaque builds up and reacts with sugars from food, creating a conducive environment for bacterial activity.

2. Acid Production by Bacteria

Bacteria in plaque convert sugar into acid, which gradually erodes the enamel by depleting essential minerals, making the enamel weak and vulnerable.

3. Enamel Demineralization

When acid continuously removes minerals from enamel, the tooth’s outer protective layer begins to break down, leading to early-stage cavities.

4. Cavity Formation & Pulp Infection

If left untreated, the decay penetrates deeper into the dentin and can eventually reach the pulp, leading to infections, severe pain, and possibly requiring tooth extraction.

Causes of Tooth Decay

Tooth decay is caused by several factors that facilitate bacterial growth, including:

Poor brushing habits – Not brushing teeth properly or frequently enough allows plaque and food debris to accumulate in hard-to-reach areas.
High sugar and carbohydrate intake – Sugary foods, carbonated drinks, and processed foods provide a prime energy source for bacteria.
Low saliva production or dry mouth (Xerostomia) – Saliva helps wash away bacteria and neutralize acids; reduced saliva increases the risk of cavities.
Certain medications – Some medications, such as antihypertensives or decongestants, can cause dry mouth, which raises the risk of decay.
Genetics and tooth structure – Some individuals naturally have tooth alignment or spacing that makes cleaning more difficult, increasing susceptibility to decay.

Symptoms of Tooth Decay

Tooth decay symptoms typically progress through four stages:

Early stage – White spots or slight yellowish patches on the enamel, with no noticeable pain.
Second stage – The tooth begins to develop cavities, causing sensitivity to cold or sweet foods.
Third stage – The decay deepens, leading to pain, cracks, or tooth fractures.
Final stage – The decay reaches the pulp, causing severe toothache, possible abscess formation, and gum swelling.

Effects of Tooth Decay on Overall Health

Tooth decay doesn’t only affect oral health but can also have systemic consequences. If left untreated, it may lead to severe health complications

🦷 1. Gum Disease and Tooth Loss

When decay is left untreated, bacteria can spread to the gums, causing periodontal disease (Periodontitis) and potentially leading to tooth loss .

Loose or missing teeth – Severe gum inflammation can weaken tooth support, causing mobility.
Abscess and gum infections – Decay can spread, leading to pus accumulation in the gums.
Bone loss in the jaw – Chronic gum disease can erode the bone supporting the teeth.

💔 2. Heart Disease and Circulatory Issues

Research has found a connection between tooth decay, gum disease, and heart conditions, as bacteria from the mouth can enter the bloodstream, leading to systemic inflammation.

Increased risk of atherosclerosis – Bacteria from decayed teeth can travel through blood vessels and contribute to arterial plaque buildup.
Higher risk of heart disease – Studies show that individuals with chronic gum disease are at a greater risk of heart disease.
Risk of endocarditis – Bacteria entering the bloodstream may infect the heart lining, causing life-threatening inflammation.

🍽 3. Digestive System Issues

Tooth decay can impair chewing, leading to digestive issues.

Strained digestion – Inadequate chewing forces the stomach to work harder.
Increased risk of acid reflux and gastritis – Poorly chewed food may irritate the stomach lining.
Potential nutritional deficiencies – Difficulty chewing certain foods, like fibrous vegetables, may lead to inadequate nutrient intake.

🤕 4. Severe Infections Spreading Through the Body

Untreated tooth decay can cause widespread bacterial infections.

Sinus infections – Decay in upper molars can lead to sinusitis.
Lung infections (Pneumonia) – Bacteria from the mouth can be inhaled into the lungs, causing pneumonia.
Sepsis (Blood infection) – Bacteria from dental infections can enter the bloodstream, leading to life-threatening sepsis.

🧠 5. Brain and Nervous System Impact

Oral bacteria can potentially affect brain function.

Increased risk of Alzheimer’s disease – Studies suggest a link between oral bacteria and neurodegenerative conditions.
Risk of brain abscess – Bacterial infections originating from decayed teeth can spread to the brain, causing abscesses.

😨 6. Quality of Life and Mental Health Effects

Tooth decay can also impact self-esteem and overall well-being.

Loss of confidence in speaking and smiling – Decayed or broken teeth may cause embarrassment.
Increased stress and anxiety – Chronic tooth pain can contribute to emotional distress.
Sleep disruption – Severe tooth pain can interfere with sleep quality.

Why Is Dental Care Important?

Tooth decay can lead to more than just oral health issues—it can impact the entire body. :

Preventing cavities is essential and can be achieved through

Brushing twice daily with fluoride toothpaste.
Flossing daily to clean between teeth.
Reducing sugar intake to minimize bacterial growth.
Drinking plenty of water to encourage saliva production.
Visiting the dentist every six months for regular checkups and preventive care.
