To get the best clean, ensure you are using the right technique.
Did you know the brush head needs to align with the teeth at an angle of 45 degrees?

How to use interdental brushes
The way in which you use interdental brushes varies slightly depending on whether you are cleaning the inter-proximal spaces of the front and rear teeth..
The key steps with both front and rear interproximal spaces is to:
Gently insert the appropriately sized brush into the space between the teeth, at gum level. Twist the brush slightly in a clockwise direction to help the brush access and fit into the gap. This can too prolong the life of the brush.
When inserted, gently move the brush in a backwards and forwards motion, the full length of the brush. Repeat this several times to remove plaque and debris.
More detailed tips and explanation, particularly on reaching the rear teeth is available here in our extensive explanation into interdental brushes.
This video from Andre Hedger does too provide some useful insight and tips.

Should you use mouthwash? This is optional, it is not necessary, but there may be benefits that you wish to take advantage of.
Mouthwash is not a replacement to your normal tooth brushing and flossing routine.
You should NOT use it straight after brushing either. Use at another time of day where you want a refresh but will unlikely be brushing, say just after lunch.
There are a few misunderstandings about mouthwash — learn more about what it offers and those that we recommend in our best mouthwash article.

How to use dental floss
The exact approach you take to floss your teeth can vary slightly depending on the type of flossing product used and the size of the gaps between teeth..
When using regular dental floss, be that sting or tape, the approach to follow is:
- Step 1: Pull out and cut off the reel of floss about 18 inches (45cm)
- Step 2: Wrap the ends around your two pointer fingers, and stretch it between them, so it is fairly taught, leaving about 6 inches between the two fingers.
- Step 3: Gently position the floss in between teeth, flex the floss slightly so it cups around the edge of one tooth in an C like shape. Move the floss up and down to get rid of plaque. Repeat this for the tooth on the other side of that same gap.
- Step 4: Repeat this for the tooth on the other side of that same gap.
- Step 5: Repeat this process for all teeth and gaps in the mouth.
- Step 6: Dispose of the floss.
