This term, 3rd and 4th grade students did an experiment to discover the effects of sugar on our teeth.
This is what happens if you don’t brush your teeth after eating sugary food! Click on the picture to open the album.
First, we did some research about the effects that sugar has on our body, not just our teeth!
Secondly, we looked at the nutritional information of different beverages to find out how many grams of sugar do they contain.
| Drink | Grams of sugar / 100ml |
| Water | 0g |
| Fanta | 5,4g |
| Coke | 10,6g |
| Chocolate milkshake | 11,4g |
| Peach juice | 12,3g |
We were shocked to discover the peach juice was the drink with more sugar in it!
Then, we did an experiment where we soaked white shelled eggs (to simulate our teeth) in the different drinks for several days. We didn’t soak one of the eggs to have as control (to compare it with the ones that were soaked),
Finally, we took out the eggs from the beverages, and we observed what had happened to the shells of the eggs. We were surprised!
But, can we solve it by brushing our teeth? We tried brushing the eggs with toothpaste, and it improved, but it wasn’t as white as the control egg.
Conclusion of the experiment: The best solution is to reduce the amount of sugar we eat and to brush our teeth after each meal.

Aquest trimestre, l’alumnat de 3r i 4t ha fet un experiment per descobrir els efectes del sucre a l’esmalt dental.
Primer, vam fer una recerca sobre els efectes del sucre a la nostre salut, no només a les dents!
Després, vam mirar la informació nutricional de diferents begudes per descobrir quants grams de sucre contenen.
| Beguda | Grams de sucre/ 100ml |
| Aigua | 0g |
| Fanta | 5,4g |
| Coca-cola | 10,6g |
| Batut de xocolata | 11,4g |
| Suc de préssec | 12,3g |
Ens vam quedar sobtats en descobrir que el suc de préssec era la beguda que més sucre tenia!
Llavors, vam fer un experiment on vam posar en remull ous de closca blanca (per simular les nostres dents) en diferents begudes durant uns dies. Vam deixar un ou sense remullar per fer-lo servir de control (per comparar-lo amb els que vam remullar).
Finalment, vam treure els ous de les begudes i vam observar què havia passat a les closques dels ous.
Això és el que passa si no et rentes les dents després de menjar aliments ensucrats! (vegeu les imatges).
Però, podem solucionar-ho raspatllant-nos les dents? Vam provar de raspatllar els ous amb pasta de dents i va millorar, però no vam aconseguir que quedés igual de blanc que l’ou de control.
Conclusió de l’experiment: La millor solució és reduir la quantitat de sucre que consumim i raspatllar-nos les dents després de cada àpat.
