Seven Ways to Prevent Dental Caries in Your Child

Dental caries is an endemic disease in children. It is caused by bacterial infection. The causative bacteria are known as Streptococcus Mutans and Lactobacilli.

Although, the dental caries is caused by bacteria, the initiation and progression of dental caries depend on several factors. The less the risk factors present, the less are the chances of dental caries development in your child's teeth.

I shall discuss those factors for you so that you can understand the developmental process of dental caries and take appropriate measures to prevent developing it in your Son’s or daughter’s mouth.
Broadly, we can categorize a child belonging to either high risk or low risk category. The children of high risk category have higher chances of developing dental caries compared to those of lower category.

The factors that determine the risk category of a person are as follows:

  1. Social factors
  2. General Health Factors
  3. Dietary factors
  4. Preventive Factors
  5. Plaque factors
  6. Salivary factors
  7. Clinical factors

1. Social Factors
A socially deprived or isolated child with frequent snacking habit, irregular dental visits, siblings having dental caries, with parents having little knowledge of dental disease, will be at higher risk of developing dental careers compared to the child who is not having the above mentioned factors. You should always try to remove and maintain these factors at low level to keep your child in low category.

2. General Health Factors
If your child is medically compromised, disabled, having xerostomia or on long term cariogenic medicine, s/he is at higher risk of developing caries. The lesser number of factors present with your child, the risk of developing dental caries is less. If your child is having any of these factors, help him/her to remain into low risk category.

3. Dietary Factors
The most important factor is frequent intake of sugars. As the frequency of sugar increases, the risk goes up. So, encourage your child to reduce the frequency of sugar intake. For example, you can give him/her two chocolates/candy instead of one and encourage him/her to eat them all together. Afterwards, you can clean his/her teeth off sticky chocolates/candy.

4. Preventive Factors- Uses of Fluoride/CPP-ACP
If your child is living in non-fluoridated area, with no fluoride supplementation and using non-fluoridated tooth paste, s/he is at high risk. Living in an area supplied by fluoridated water, or using fluoride supplement or using tooth paste containing fluoride decreases the risk for caries development.
The newly developed protective material Casein phosphopeptide-amorphous calcium phosphate (CPP-ACP), a milk derivative helps in remineralization of the carious lesion by replenishing lost minerals like calcium, phosphate ions into the tooth structure. Using a toothpaste containing CCP-ACP will re-mineralise the enamel of your child and make it more resistant to caries development.

5. Plaque Control Factors
If your child does infrequent or ineffective tooth brushing s/he is at higher risk. Teaching him or her regular and effective tooth brushing to remove plaque. This habit decreases the risk of developing tooth decay. If s/he cannot perform effective tooth brushing, help him/her.

6. Salivary Factors
Low flow of saliva, low buffering capacity of saliva and higher Streptoccus Mutans and Lactobacilli count in saliva put your child in high risk category. Removing these factors with the help of a dentist will shift your Son/Daughter into low risk category.

7. Clinical Factors
New carious lesions, premature extractions, caries or restorations (fillings) in anterior teeth, multiple restorations, history of repeated restorations, no fissure sealants, multi-band orthodontics and presence of partial dentures increase the risk of caries development and put the child in high risk. As these factors decrease, the child moves from high to low risk category.


So, now you know the causes that may put your child at high risk for developing dental caries. I advise you to understand these factors and take appropriate action. The first step you must take is to start using a toothpaste that contains either fluoride or CCA-ACP. To buy a good toothpaste you can choose any of the following link.

Inferior Dental Nerve Block

The inferior alveolar nerve is also known as inferior dental nerve.  it gives of a motor branch that supplies to mylohyoid muscle and anterior Belly of digastric.  then it travels through mandibular foramen and enters the mandible why are the inferior dental canal.  from inferior dental Canal it supplies to mandibular Third molar, second molar, first molar, and second premolar.

From the level of second premolar it moves forward as mental nerve and exits through mental foramen.  the mental nerve supplies sensory nerve fibres to the chin and lower lip of that side. within the mandible after mental foramen it moves forward as incisive nerve and give sensory supply to mandibular incisors and mandibular canine of that side.

Anatomical landmarks of inferior dental nerve block:

  • mucobuccal fold
  • external oblique Ridge
  • anterior border of mandibular ramus
  • internal oblique Ridge
  • retromolar Triangle
  • pterygomandibular ligament
  • buccal pad
  • pterygomandibular space

Nerves anesthetized by inferior dental nerve block:

  • inferior dental nerve and its subdivisions
  • mental nerve
  • incisive nerve
  • lingual nerve
  • buccinator nerve

Area  anesthetized by inferior dental nerve block

  • lower portion of the ramus and body of the mandible
  • mandibular teeth incisors canines premolars and molars
  • Mucous membrane and underlying tissues anterior to the mandibular first molar ( supplied by lingual nerve)


To numb the soft tissues posterior to the buccal aspect of first molar the long buccal nerve should be  anaesthetised.

Indications of inferior dental nerve block:

  • root canal treatment, implant  surgery, flap surgery, extraction of teeth or any other surgical procedure on mandibular teeth.
  • surgical procedure on soft and hard tissues anterior to the first mandibular molar.  in this case both inferior alveolar nerve and lingual nerve should be blocked.
  • surgical procedure performed on soft tissues and heart issues posterior to the first mandibular molar.  in this case both inferior dental nerve and long buccal nerve, both should be a anaesthetised.
  • in diagnosing pulp vitality,  Trigeminal Neuralgia et cetera.

Way of the needle during insertion for inferior dental nerve block:

the needle passes through mucosa,  thin sheet of buccinator muscle, loose connective tissue and fat.

Structures in neighbourhood of the needle when it is in final position:

  • inferior alveolar arteries and veins
  • inferior alveolar nerve
  • inferior portion of the internal pterygoid muscle
  • myelohyoid artery and veins
  • mylohyoid nerve
  • the needle is present anterior to the deep part of parotid gland
  • the needle is present medial to the  ramus of the mandible
  • the needle is present lateral to 1. Lingual nerve 2. internal pterygoid muscle. 3. sphenomandibular ligament

Symptoms of anaesthesia in inferior dental nerve block:

Subjective symptoms:

tingling sensation and numbness of the lower lip, and tip of the tongue when lingual nerve is also anaestheised.

Objective symptoms:

instrumentation should be done. Use either the tip of a blunt probe or elevator to check for objective symptoms.   The anaesthetic tissue and teeth should be pressed and tapped as compared to the normal side without anaesthesia.

Complications of inferior dental nerve block:

One or several of the given  below complications may develop  during inferior alveolar nerve block.

  • muscle trismus
  • Hematoma
  • needle breakage
  • mucosal irritation
  • transient hemifacial paralysis

How Healthy Teeth Help You to Stay Healthy

By Susan Cruise

The relationship of the teeth to general health and efficiency was appreciated in a general way long before vitamins or focal infections had been heard of. Toothaches used to be as inevitable as colds; and slave buyers and horse traders inspected the teeth of their prospective purchases before buying.
