Flashcards in Dental Conditions Deck (76):
What are different dental conditions?
What are the symptoms of teething pain?
Gum redness, swelling or tenderness
Drooling, rubbing the gum, flushed cheeks because of mild increase in body temperature
Irritability restlessness, crying, insomnia, decreased appetite, increased thirst
What are NOT symptoms of teething pain?
Fever (although there may be slight elevation of temperature)
Diarrhea (although there may be loose stools)
Common cold symptoms
When do teething symptoms begin?
Symptoms can begin up to 4 days prior to the eruption of the tooth
What are some non pharmacological treatments for teething?
Rub the baby's gums by using a clean finger or a damp washcloth to massage the gums
Cool the affected area by letting the chew on a frozen facecloth or a cold pacifier/teether (avoid contact with extreme cold; don't freeze pacifiers)
Wipe the baby's face often with a cloth to remove the drool and prevent rashes from developing
What are some pharmacological options for teething pain?
Acetaminophen 10-15 mg/kg/dose q4-6h prn (max 65 mg/kg/day)
Ibuprofen 5-10 mg/kg/dose q6-8h hours prn (max 40 mg/kg/day)
Refer if no relief with treatment after 3 to 5 days
What are some topical anesthetic products that can be used for teething pain?
Benzocaine gel (Baby Orajel 7.5%, Baby Orajel Night time 10%, Baby Anbesol 7.5%)
Should topical anesthetics be used for teething pain?
They only provide relief for a maximum of 45 minutes
They are controversial due to potential harm. They inactivate the gag reflex, which increases the risk of choking. They are a sensitizers. In some cases, they can cause Methemoglobineia; the benzocaine can prevent oxygen from binding to the blood cells (requires a genetic polymorphism). This can cause shortness of breath, blue lips and even death
What causes symptoms of a toothache?
Symptoms that may be due to a variety of causes.
Cracked tooth has abrupt pain with biting and resolves with removal of pressure (requires a referral to the dentist for assessment and treatment)
Post-dental procedure discomfort

Benzocaine (OraJel regular (10%), Maximum strength (20%), PM (20%), Anebsol Liquid/gel (20%)
What is tooth hypersensitivity?
Short, quick sharp dental pain due to exposure to a stimulus (thermal, chemical, osmotic, physical) on exposed dentin
A dental referral is necessary to determine (and potentially treat) the underlying cause
What does tooth hypersensitivity result from?
May result from: "tooth decay, fractured teeth, worn fillings, gum disease, worn tooth enamel or an exposed tooth root due to gum recession"
What are some non-pharmacological suggestions for tooth hypersensitivity?
Reduce acidic foods and drinks
What are pharmacological options for tooth hypersensitivity?
Desensitizing toothpaste work by blocking the repolarization of the nerve fibre membranes, thereby decreasing the pain
Key ingredient: potassium nitrate
Product examples: Sensodyne F, Crest-Pro Health, Colgate Sensitivity
What is oral candidiasis?
Also known as thrush
Most commonly caused by C. albicans

Other organ involvement such as conjunctivitis, uveitis or accompanying genital ulcers
Any lesion present for 3 weeks or longer should be referred to physician as it may require biopsy and/or systemic antifungal treatment
Possible symptoms of an adverse drug reaction. If a prescription medication is suspected, refer to physician for evaluation and possible change in medication
Suspect another type of infection (e.g., viral herpes infection)
Unable to confirm diagnosis of oral thrush. Refer for further evaluation and/or physician-supervised therapy
Treatment unsuccessful after 14 days
