Tooth Decay

Despite the frequency of tooth decay, it is a preventable condition that can be managed with the right oral health care and attention. At our Portland City Dental dental office, we're dedicated to helping our patients understand the causes of tooth decay, recognize the warning signs, and take proactive steps to maintain a healthy and beautiful smile.

What is Tooth Decay?


Tooth decay, also known as dental caries or cavities, is the destruction of the tooth enamel. Tooth enamel is the hard, outer layer of your teeth. Tooth decay occurs when harmful bacteria in the mouth produce acids that erode the enamel, leading to the formation of holes or cavities. If left untreated, tooth decay can progress deeper down into the tooth, affecting the dentin and pulp, which may result in pain, infection, and even tooth loss.

Tooth decay can develop slowly and often without noticeable symptoms in the early stages. That's why regular dental checkups with us are essential for catching issues early on, allowing us to treat them, and prevent more serious damage from occurring.

What Causes Tooth Decay?


Tooth decay is caused by a combination of factors that create an environment in your mouth where bacteria can thrive. These factors can include the following:

Poor Oral Hygiene


Failing to brush and floss regularly allows plaque, which is a a sticky film of bacteria, to build up on your teeth. Over time, this bacteria breaks down sugars from the food you eat and produces acid that wears away enamel.

Sugary and Acidic Foods and Drinks


Consuming foods and beverages high in sugar and acid, like soda, candy, and citrus fruits, can accelerate enamel erosion and promote bacterial growth.

Dry Mouth


Saliva helps neutralize acids in the mouth and wash away food particles. When you have dry mouth (the medical term is xerostomia), you're more prone to plaque buildup and tooth decay.

Deep Grooves and Pits in Teeth


Some people naturally have deep grooves in their molars, which can trap food and bacteria more easily, making them more susceptible to the development of decay.

Age and Certain Medical Conditions


Children and older adults are often at higher risk of developing tooth decay, as are individuals with medical conditions such as diabetes or acid reflux that affect the mouth's environment.

Signs of Tooth Decay


Tooth decay can go unnoticed until it becomes more advanced. Knowing the symptoms can help you seek treatment early, before it leads to more serious dental problems.

Be sure to keep an eye out for these common signs of tooth decay:
•  Toothache or spontaneous pain without an obvious cause
•  Tooth sensitivity when eating or drinking something hot, cold, or sweet
•  Visible holes or pits in your teeth
•  Brown, black, or white staining on the surface of a tooth
•  Pain when biting down or chewing
•  Bad breath or a persistent bad taste in the mouth, regardless if your brush

If you experience any of these symptoms, schedule an appointment with Portland City Dental as soon as possible. Early intervention can save your tooth and prevent infection.

Treatments for Tooth Decay


The treatment for tooth decay depends on the severity of the problem. Here are the most common approaches we use:

Fluoride Treatments


In the earliest stages of tooth decay, fluoride treatments can help remineralize enamel and stop the decay from progressing. These are stronger than over-the-counter fluoride toothpaste and mouth rinses.

Dental Fillings


If a cavity has formed, your dentist will remove the decayed portion of the tooth and fill the space with a composite resin, amalgam, or other suitable material.

Crowns


When decay is extensive and has weakened the tooth, a dental crown, also commonly referred to as a tooth cap, may be necessary to restore its shape, strength, and function.

Root Canal Therapy


If decay has reached the pulp of the tooth, causing infection or severe pain, a root canal procedure may be required to remove the damaged tissue and seal the tooth.

Tooth Extraction


In cases where the tooth is too damaged to be restored, your dentist may recommend removing it entirely and exploring replacement options like dental implants or bridges.

How to Prevent Tooth Decay


Preventing tooth decay is easier than treating it. With consistent, good oral hygiene habits and regular professional dental care, you can protect your teeth from decay and enjoy a healthy smile.

Here are some essential prevention tips, to help protect you from developing tooth decay:
•  Brush your teeth twice a day with fluoride toothpaste (preferably after you eat)
•  Floss daily to remove plaque between teeth and along the gumline (nighttime is the best time, just before you go to bed)
•  Limit sugary snacks and drinks, especially between meals
•  Drink water regularly, especially if you suffer from dry mouth
•  Chew sugar-free gum to stimulate saliva production
•  Visit your dentist regularly for cleanings and checkups
•  Consider dental sealants for children or adults with deep grooves in their molars

Our dentist, Dan Rodriguez, or Dr. Dan as he is known to his patients, can also recommend personalized preventive strategies based on your risk factors and oral health needs.
