Scary Facts About Teeth: What You Don’t Know Could Hurt You

Teeth may seem like simple tools for chewing, but there’s a lot more to them than meets the eye. While they’re essential for eating, speaking, and even smiling, neglecting proper care can lead to some truly frightening consequences. From hidden bacteria to risks that extend beyond your mouth, your teeth deserve more attention than they often get. At Lifetime Smiles Cosmetic Dentistry, Dr. Arzegar and his team are here to help you keep your teeth and gums healthy—and to shine a light on some scary facts about what happens when oral hygiene is ignored.

Here are some surprising, and a bit unsettling, truths about teeth that might just inspire you to take extra good care of your smile.

‍

1. Cavities Are Contagious

Believe it or not, cavities can be contagious! The bacteria responsible for tooth decay, Streptococcus mutans, can transfer from one person’s mouth to another’s through saliva. Sharing utensils, kissing, or even tasting food from the same spoon can spread these cavity-causing bacteria.

How to Protect Yourself:

• Avoid sharing eating utensils or drinks.
• Make sure everyone in your household practices good oral hygiene.
• Regular dental cleanings help reduce bacteria levels, lowering the risk of spreading decay.

‍

2. Gum Disease Can Affect Your Whole Body

Gum disease doesn’t just stop at the gums. Infections in your mouth can enter the bloodstream, potentially leading to systemic health issues like heart disease, diabetes, and respiratory conditions. Research has linked advanced gum disease (periodontitis) to increased risk of heart attacks and strokes.

How to Protect Yourself:

• Brush and floss daily to keep plaque and bacteria under control.
• Get regular periodontal check-ups to catch gum disease early.
• Don’t ignore bleeding gums; they may be a sign of infection.

3. Acid Can Dissolve Tooth Enamel Permanently

Your tooth enamel is incredibly strong—stronger than bone, in fact. But it’s also vulnerable to acid erosion, and once it’s gone, it can’t grow back. Acidic foods, sugary drinks, and even certain fruits can soften and erode enamel, leaving your teeth more susceptible to decay and sensitivity.

How to Protect Yourself:

• Rinse your mouth with water after consuming acidic foods or drinks.
• Limit sugary and acidic beverages like soda, sports drinks, and fruit juice.
• Use a toothpaste with fluoride to help strengthen enamel.

4. Teeth Grinding Can Shorten Your Teeth

Bruxism, or teeth grinding, can wear down your teeth over time, leading to short, flat teeth and even fractures. Many people grind their teeth unknowingly, often while they sleep, which can also lead to jaw pain, headaches, and temporomandibular joint (TMJ) issues.

How to Protect Yourself:

• If you wake up with a sore jaw or frequent headaches, talk to your dentist about bruxism.
• A custom night guard can protect your teeth from grinding damage.
• Stress management techniques can also reduce nighttime grinding.

5. Plaque Hardens Into Tartar Within 24 Hours

Plaque is a sticky film of bacteria that builds up on teeth daily, but if it’s not removed through regular brushing and flossing, it can harden into tartar within just 24 hours. Tartar is much harder to remove and can only be cleaned off by a dental professional. When left unchecked, it irritates gums, leading to inflammation and gum disease.

How to Protect Yourself:

• Brush twice a day and floss daily to prevent plaque from hardening.
• Schedule professional cleanings every six months to remove tartar.
• Consider an electric toothbrush, which may help remove plaque more effectively.

‍

6. Tooth Decay Is One of the Most Common Diseases

Tooth decay is one of the most widespread health problems, affecting people of all ages and backgrounds. According to the World Health Organization, untreated dental decay affects nearly 3.5 billion people worldwide. It can lead to pain, infections, and even tooth loss if left untreated.

How to Protect Yourself:

• Limit sugary snacks and drinks, which feed bacteria that cause cavities.
• Use fluoride toothpaste, which strengthens enamel and prevents decay.
• Get regular check-ups to catch cavities early and treat them before they progress.

‍

7. Neglected Tooth Infections Can Be Life-Threatening

An untreated tooth infection, such as an abscess, can spread to surrounding tissues and even enter the bloodstream, potentially leading to life-threatening conditions like sepsis. If a toothache is accompanied by fever, swelling, or a foul taste, it may be a sign of an infection that requires urgent attention.

How to Protect Yourself:

• Don’t ignore tooth pain or swelling—see your dentist as soon as possible.
• Seek treatment for cavities and decay before they lead to infection.
• Good oral hygiene habits can prevent infections from developing in the first place.

8. Your Teeth Are a “Window” to Your Overall Health

Your oral health can reveal clues about other health issues. Certain conditions, such as diabetes, osteoporosis, and even certain cancers, can show early signs in your mouth. Regular dental check-ups aren’t just about your teeth—they’re an opportunity to monitor your overall health.

How to Protect Yourself:

• Stay consistent with dental visits, as your dentist may spot early signs of health issues.
• Inform your dentist of any new health conditions, as they may impact your oral health.
• Prioritize oral care as part of your overall wellness routine.

‍

9. Once Your Baby Teeth Are Gone, That’s It

Adult teeth are irreplaceable, and once they’re damaged or lost, they don’t grow back. It’s essential to protect your natural teeth with preventive care, as missing or damaged teeth can impact chewing, speech, and even your jaw structure over time.

How to Protect Yourself:

• Avoid using teeth as tools to open packages or bite on hard objects.
• Wear a mouthguard during sports or physical activities to protect against trauma.
• Brush, floss, and get regular cleanings to keep your natural teeth healthy and strong.

Our Cosmetic Dentistry and Dental Implants services can help restore and protect your smile if you’ve lost or damaged teeth.
