Make your own toothpaste and compare it with other brands
First things first, you need a recipe for toothpaste. You could find your own by searching on the internet. Try typing things like ‘homemade toothpaste’ into a search engine.
Investigate the effectiveness of different toothpastes
You should start by writing down the ingredients of numerous different brands of toothpaste and how much they cost. Compare them. Decide which you think gives the best value for money. How do the compositions of toothpastes vary? Do toothpastes that claim to remove stains from smoking, for example, have any different ingredients? What are they? Try to find out what the various ingredients do. Choose a few different brands to test.
Investigate and compare the properties of toothbrushes
To start this project it may be a good idea to look at a range of different toothbrushes available. Look at their different shapes. Look at what they claim to do (for example, certain bends or bristle shapes are supposed to reach areas that other brushes can’t reach). Other things to look at include:
- how many ‘grades’ of hardness there are for the bristles.
- which ones are the most expensive. How does the price of regular toothbrushes compare to electric toothbrushes (indeed, what’s the price range of electric toothbrushes)?
- what other products are available for teeth-cleaning purposes?
