First, we need to determine how much money David has left after buying the shirt.

David starts with $90 and spends $25 on a shirt:

\[
90 - 25 = 65
\]

Now, David has $65 left to spend on chewing gum. The price of one piece of chewing gum is $3. To find out how many pieces he can buy, we divide the remaining money by the price of one piece of gum:

\[
\frac{65}{3} = 21.67
\]

Since David can only buy whole pieces of chewing gum, we round down to the nearest whole number:

\[
21
\]

Thus, the maximum number of pieces of chewing gum David can buy is **21**.
