How to Treat Common Dental Problems in Kids and Older Adults?

Healthy Smiles at Every Age

The first tooth begins to erupt, while the last “real” tooth comes out, and both require the same care: attentive age-appropriate dental care. Children are in the process of developing their teeth, jaws and habits. As time goes on, older people are coping with decades of wear, medications, gum recession, and sometimes even tooth loss. Each group has a set of dental issues and the safest and best treatment for each issue differs for each group.

Knowing about the issues to watch out for and when to take action can help protect smiles from one generation to the next. The Smile Designers brings you the most frequent dental issues in kids as well as older adults, the indications to look out for, and how each is handled.

Clarifying some dental problems that are common among children.

Part 1: Common Dental Problems in Kids

Primary (baby) teeth may be temporary, but they matter enormously. They help children chew and speak clearly, hold space for the permanent teeth, and guide those teeth into position. Infections in baby teeth can also affect the developing permanent teeth beneath them. Dental care therefore should begin early. Many pediatrics dental bodies recommend a first visit by the child’s first birthday, or when the first tooth appears.

1. Early Childhood Cavities

One of the most prevalent chronic health issues in children is tooth decay, and it can start to occur very early in their development after the first teeth come in. The enamel on baby teeth is thinner and will decay more quickly. Sweets and drinks, juice or milk from a bottle throughout the day, falling asleep with the bottle and poor brushing are risk factors.

Symptoms: White chalky lines around the gums, brown or black spots, sensitivity, a child not eating certain foods or saying that their tooth hurts.

Treatment: If the treatment is begun very early, sometimes the problem can be prevented with fluoride varnish and proper brushing and flossing. Fillings for children are used to fill up established cavities. A pulpotomy is a very simple procedure that can be used to treat the infected part of the pulp, helping to save the tooth, and the tooth is then usually covered by a crown. If the tooth is too badly damaged it can be removed and a space maintainer will be placed in the gap to allow room for the permanent tooth to erupt.

Prevention: Brush twice a day using a pea-sized amount of fluoride toothpaste for children ages 3-6, and a smear for children under 3, and a 3 mm line of toothpaste. Let children brush their teeth until they are 7 or 8 years old, don’t offer sugary snacks outside of meals, and don’t give your child a bottle of anything other than water at bedtime. Sealants are thin, plastic coatings that seal the grooves of the back teeth and can prevent cavities. 

2. Gum Inflammation

Children can also get gingivitis, especially if they allow plaque to build up around the gum line. The typical symptoms are swollen, bleeding, red gums. The great news is that gingivitis in pediatrics is easily treated with proper brushing and flossing and flash cleaning. Flossing early makes sure that it doesn’t follow them into adulthood; helping children until they can do it themselves.

A number of teething and eruption issues may arise.

Teething may cause infants to be fussy, drooling and uncomfortable. Teething rings that are chilled (not frozen) and gentle massaging of the gums can be helpful. Later a problem may occur if permanent teeth grow in the wrong position, if baby teeth are shed too early or too late. If a permanent tooth is growing in behind a baby tooth that hasn’t fallen out before it comes in, which is often the case in front lower molars, it is common but can require a dentist to extract the baby tooth if it has not fallen out soon.

3. Thumb sucking, Pacifier use and mouth breathing.

These habits are typical in infants, and can cause the front teeth to move forward, making the top jaw narrow and causing an open bite if these habits are continued beyond the age of about 3-4 years. When someone breathes out of their mouth for extended periods of time, which is frequently associated with large tonsils or allergies, this can also have an impact on jaw development and also raise the likelihood of cavities and gum inflammation.

Treatment: Punishment is generally not appropriate; positive reinforcement and gentle reminders are likely to be more effective. Habit breaking appliances may be recommended by the dentist if necessary and a speech and language therapist evaluation may be recommended for mouth breathers.

4. Crooked Teeth and Bite Problems

Protruding teeth, bite issues and crowding are extremely widespread. An early evaluation (around age 7) is when a dentist has the chance to identify growth issues while the jaws are still in the process of developing. Treatment may be easier or shorter if simple appliances are used to guide some issues at an early stage. A comprehensive braces or aligner treatment is typically then designed when more of the permanent teeth have erupted. Our clinic can help you determine the best time for each child with our Invisalign providers and an orthodontist guiding the team.

5. Dental Injuries

Falls, sports and play cause many chipped, cracked or knocked-out teeth. First aid matters:

Chipped tooth: Rinse the mouth, and if possible, preserve the tooth fragment. Visit your dentist as soon as possible.

  • Knocked-out permanent tooth: Pick it up by the crown, not the root. If soiled, rinse it off with gentle water, do not scrub it, and attempt to reinsert into the socket or hold in the milk. Seek a dentist’s attention right away, the first hour is important.

Do not put a knocked out baby tooth back in. Visit dentist to see if it is damaged.

A contact sport’s athlete can avoid most of these injuries by wearing a mouthguard.

6. Dental Anxiety

Many children are afraid of going to the dentist and this can start when they have an unpleasant or hurried first visit. Early, routine check-up visits to the dentist when children do not experience pain, make it more of a routine and familiar part of their life. Clinics are geared towards children with calm language, show and tell explanations and gentle techniques to build trust. To ensure that every visit at our pediatric dentistry clinic in Chandigarh and Mohali is a relaxed one, our team of pediatric dentists works towards it.

Part 2: Common Dental Problems in Older Adults

With better dental care, more people are keeping their natural teeth for life. But age brings its own set of challenges, from medications and medical conditions to years of cumulative wear. Many older adults also assume that tooth loss, sensitivity or dry mouth are inevitable parts of ageing. They are not. Most can be prevented or managed.

1. Dry Mouth

Saliva helps preserve the health of teeth and gums, but many older people experience a decrease in saliva production, typically as a result of medications used to treat high blood pressure, depression, allergies, pain and other conditions. Chewing, swallowing and speaking becomes difficult, gum disease, oral infection and bad breath become more likely, and a dry mouth is more likely to cause tooth decay.

Treatment and management: Drink plenty of water, chew sugar free xylitol gum or lozenges, do not use alcohol mouthwash or tobacco and use saliva substitutes as prescribed. Professionally applied fluoride or high fluoride toothpaste provides additional protection. Check with the doctor that prescribed medicines, don’t stop the medicines without permission.

2.Root Decay and Cavities

Gums recede with age, exposing the softer surfaces of the root of the teeth. Roots are more susceptible to decay due to the lack of the “crown’s” protective enamel. Old fillings and crowns are another place where cavities are likely to form.

Treatment: If the root decay is early, it can be controlled by fluoride and better cleaning. Fillings or crowns are required for these larger areas, and if the tooth becomes infected, root canal treatment may often be necessary to save the tooth. The key to prevention is fluoride, attention to brushing at the gumline and routine check-ups.

3. Gum Disease

Gum disease is one of the most common causes of adult tooth loss, and increases with age, smoking, diabetes and poor oral hygiene. The most prominent symptoms are bleeding, swollen or receding gums, bad breath, and loose teeth.

Treatment: Early disease is treated by professional cleaning and good home management. Advanced gums disease requires deep cleaning (scaling and root planing) and ongoing treatment intervals, and in some cases surgical gum treatment. Controlling diabetes and quitting tobacco greatly improve results.

4. Tooth Wear, Sensitivity and Cracks

Night-time chewing and grinding habits and food additives containing acids thin down enamel.Food additives with acid or chewing and grinding during the night thin enamel over decades. Old fillings may fail, teeth may become flat, chipped, sensitive or cracked. Many people complain about sensitivity to hot and cold.

Treatment: Desensitising toothpaste and fluoride should help mild sensitivity. A night guard prevents teeth from grinding, and worn or broken teeth can be treated with bonding, onlays, or crowns and veneers. Crowns and bridges can help to restore strength and appearance to damaged teeth.

5. Loss of teeth and poorly fitted dentures

The loss of teeth is not just about the looks. They make chewing food hard, may result in low nutrient intake, may cause neighbouring teeth to move and may be a factor in bone loss in the jaws. Badly-fitted dentures can lead to sore spots, denture slipping, fungal infections beneath the denture and speech difficulty.

Treatment options:

  • Dental implants are placed into the jawbone to replace missing teeth, providing a stable and durable support. It is suitable depending on the bone health and the health of the patient and a thorough assessment is necessary. Know about Dental Implant Chandigarh.
  • A crown or bridge will be used to replace one or more teeth supported by neighbouring teeth or implants.
  • Partial or full dentures are still a very good, inexpensive option, and implant-supported dentures can provide much greater stability.

Clean dentures each day, take them out at night (unless instructed otherwise) and inspect them regularly, as the shape of a jaw changes over time and the fit loosens.

6.Oral Thrush and Denture Stomatitis

Fungal infection is more likely if you have dry mouth, dentures, inhaled steroids, antibiotics or certain health conditions. It is found as creamy white patches or as a red sore area under the denture. Treatment involves antifungal medication, strict denture hygiene and correcting any denture fit problems.

7. Oral Cancer

Oral cancer increases as people get older, especially if they use tobacco and drink a lot of alcohol. A sore or ulcer that does not heal after about two to three weeks and white or red patches, a lump, numbness or problems with swallowing are warning signs. Changes are detected by dentists during routine check-ups and early diagnosis makes a significant difference to the result. Anybody who is aware of these symptoms should be checked up immediately.

8. Medical conditions and medicines

Several other health issues such as diabetes, cardiovascular disease, osteoporosis and arthritis are related to oral health and planning treatment. Blood thinners, bisphosphonates and anti-rejection drugs, for instance, affect the way dental treatments are planned. Brushing might also be difficult due to mobility or memory problems. Be sure to give your dentist a comprehensive medical history and medication list. Geriatric dentistry service provided by prosthodontic specialists is focused on these needs.

Though different, the following rules apply at both ends of life:

  • Prevention beats repair. Careful cleaning, regular check-ups, fluoride and sealants detect problems early, when they can be treated most easily.
  • Diet matters. Bacterial decay is the result of repeated sugar use at any age. Water, dairy, fibre-rich foods are good for teeth.
  • Someone has to be there to assist. Children are supervised when brushing their teeth; caregivers might need to help older adults clean their teeth and dentures.
  • Comfort drives compliance. People are much more likely to attend if they experience a calm and un hurry, respectful dental visit.
  • The whole-body and oral health are related. Gum disease, infection and tooth loss can impact overall health, nutrition and quality of life.

Here are some tips to help you start your day in the right way and to make your day easier for everyone!

For children:

  1. Use a soft cloth to clean gums from the early days of their appearance.
  2. Flouride toothpaste and soft brushes are recommended for the proper age.
  3. Use a timer, song or sticker chart to make brushing a fun activity.
  4. Reduce juice, sweets and sticky foods, and only have them at meal times.
  5. Get a dental examination twice a year.

For older adults:

  1. Use a soft toothbrush or electric brush and fluoride toothpaste and brush between teeth every day.
  2. Clean dentures daily and take out at night if recommended.
  3. Drink plenty of water and discuss with your doctor saliva substitutes if mouth is dry.
  4. Never ignore mouth sores, loose teeth or a poorly fitting denture.
  5. Even if you have no natural teeth, have regular dental check-ups; a dentist also checks for oral cancer and for the fit of your dentures.

 When to See a Dentist Right Away

  • Swelling of the face/ fever or pus around a tooth
  • A knocked out or broken tooth
  • If toothache is severe or persistent
  • Any bleeding that does not subside.
  • Any mouth sore that does not heal within 2-3 weeks
  • Sudden difficulty chewing, swallowing or opening their mouth

Frequently Asked Questions

When is the best time for my child to get a dentist appointment?

 At 1 year of age or at 6 months after the first tooth, and then every 6 months.

Are baby teeth supposed to have fillings?

 Yes. Even the decay in baby teeth can cause pain, infection and tooth decay in permanent teeth, and make it hard to eat and sleep.

Are fluoride safe for children?

 As long as it is applied properly and in an amount that is suitable for the child’s age, fluoride makes teeth stronger and helps prevent cavities. Apply just a smear or pea-sized amount of toothpaste, and remind children to not swallow the toothpaste.

Does it appear to be that tooth loss is a natural process of ageing? 

No. The majority of tooth loss is caused by decay and gum disease, which are preventable and treatable.

Can dental implants be used with seniors? 

Often yes. Age by itself is not a barrier. Appropriateness is based on the health of the bones, gums and overall health, and a complete examination is required.

When should older people get check-ups? 

Every six months or as frequently as every three months if they have gum disease, dry mouth, dentures or have conditions that impact oral health.
