Plaque
Remember what
we said last
lesson about
plaque.
Plaque on teeth
Are these teeth clean ?
We
should
clean our
teeth
twice per
day.
But do we
always do it
properly?
Disclosing tablets
Plaque is the same colour as the teeth and hard to see. These
tablets can be used to stain the plaque a different colour.
Disclosed plaque
plaque
on
teeth
plaque on
gums
plaque
between
teeth
Plaque can cause two problems
Plaque on teeth -> tooth decay.
Plaque on gums -> gum disease.
This time we are looking at the gums.
Gum disease ( gingivitis )
1) pink gums become red
2) swollen
3) bleed when brushed
These are the 3 main
symptoms of gum disease.
Gum disease ( gingivitis )
blood
swollen
gums
To prevent gum disease
•
•
•
•
•
•
Use a medium to soft small headed toothbrush.
Change your toothbrush when worn out.
Brush effectively twice a day.
Brush for longer.
Brush all surfaces of the teeth.
Brush your gums and your teeth.
Tooth brushing
How many times a day should we brush our
teeth ? What are the best times ?
Morning and night
The two best times are…………
This is because the teeth are at their most dirty
at these two times of the day. This is your best
chance of removing most of the plaque.
Choosing a toothbrush
• Soft to medium bristles.
• Small head.
• Remember to change
when worn out after about
3 months.
Toothpaste
Standard family fluoride toothpaste.
1350ppm to 1500ppm fluoride.
Use a pea sized amount only.
ppm = parts per million
Toothbrushing
Brushing our teeth with a ‘family fluoride toothpaste’
helps with two things.
1) The act of brushing removes the plaque from
our teeth and gums.
2) The fluoride in the toothpaste helps make the
enamel on our teeth stronger and more resistant
to tooth decay.
Activity
• The large mouth model
can be used to
demonstrate how to
brush.
• Remember teeth have
several surfaces.
• Remember to brush all
the teeth and the gums
to remove all the
plaque.
Process of decay
When you eat sugar
plaque + sugar -> acid
This acid can attack the teeth
Food and Drinks High in Fat or Sugar
These foods are high in added sugars and can damage teeth.
Sticky foods can be more damaging as the sugar sticks to the teeth.
Safer snacks
fruit
vegetables
salads
cheese
bread
pasta
rice
meat
fish
Be cool in school
Water is important.
Children should switch to drinking water with
meals instead of less healthy sweetened soft
drinks which can damage teeth.
Water promotes hydration and has no calories.
Un cool drinks
coke
diet coke
fizzy drinks
milk shake
cup drinks
Sports drinks
Most contain lots of sugar.
( 5 to 8 teaspoons full )
Did you know that diet
drinks contain citric acid,
which is also not friendly to
teeth ? These drinks can
cause ‘acid erosion.’
Acid erosion
Different from tooth decay, erosion is caused by acids in drinks. The
tooth enamel is softened and then worn away by chewing.
The 3 most important things to
remember
1) Brush your teeth and gums twice a day.
2) Save all sugar to mealtimes.
3) Visit the dentist for a check up at least once a
year. (Children may be advised to go more often.)
